Arthur's notes for Air (Principles) Isotopes are elements with different numbers of neutrons, thus having different masses. But isotopes of the same element always have the same number of protons, otherwise they'd be a different element. Nucleons are the protons and neutrons combined. Daltons are the fundamental unit of mass in Alchemy. Nucleons (protons and neutrons) all have a mass of one Dalton.

- True, if it contains more than one is is not a single element but a combination of elements. We should include one caveat: elements can have different isotopes of that eleme…nt. By one definition all the isotopes are still the same type of atom since they all have the same number of protons even if they differ in the number of neutrons. If the number of protons differs you no longer have the same element.

- Each element has a specific number of protons in the nuclei of its atoms. This number is known as the atomic number for the element.For instance, the atomic number of hydrogen is one because it has a just one proton in its nucleus. The atomic number of oxygen is eight, again because it has eight protons in its nucleus.or instance, the atomic number of hydrogen is one because it has a just one proton in its nucleus. The atomic number of oxygen is eight, again because it has eight protons in its nucleus.

atomic number Scientists use the term atomic number to describe the number of protons in one atom of an element. For example, the atomic number of hydrogen is 1. If you've ever taken a chemistry class, you've seen a chart called the periodic table of elements.. It lists every chemical element and each element's atomic number. Just by looking at the table, you can see that the atomic number of oxygen is 8 — this means that there are eight protons in one atom of oxygen. In chemistry and physics, the atomic number is represented by the letter Z.

Is the number of protons and electrons equal in every element? These processes can be reversed so that the atoms are back to their neutral ground state. The number of protons is unique to the element. So a carbon with a missing proton isn't carbon, it is a boron with an extra electron. Yes, the number of protons and electrons are equal in the atoms of every element. This is essential to maintain electric neutrality of the atoms. However, this rule doesn't apply to ions. Also, the number of protons or electrons is called the atomic number and is useful to place the elements in the periodic table.

Chemical element The atomic number of an element is equal to the number of protons in each atom, and defines the element. For example, all carbon atoms contain 6 protons in their atomic nucleus; so the atomic number of carbon is 6.s a special case, the three naturally occurring isotopes of the element hydrogen are often specified as H for 1 H (protium), D for 2 H (deuterium), and T for 3 H (tritium). This convention is easier to use in chemical equations, replacing the need to write out the mass number for each atom.

Review of Elements, Compounds, and Mixtures 2. All atoms of an element are identical. 3. Atoms of different elements have different weights and different chemical properties. 4. Atoms of different elements combine in simple whole numbers to form compounds. 5. Atoms cannot be created or destroyed. When a compound decomposes, the atoms are recovered unchanged.he shorthand notation for a compound describes the number of atoms of each element, which is indicated by a subscript written after the symbol for the element. By convention, no subscript is written when a molecule contains only one atom of an element.

What Are Atoms of the Same Element That Have Different Masses Called? When an atom has a different number of neutrons, because neutrons have no electric charge, the atom's electric charge is not affected. Isotopes do have a different atomic weight, though.On the periodic table, the atomic weight, or atomic mass, is given for each element. The number is not a whole number, since it reflects the natural abundance of isotopes of an element. For example, hydrogen's atomic mass is 4.003.

Atom Atoms of the same element have the same number of protons, called the atomic number. Within a single element, the number of neutrons may vary, determining the isotope of that element. The total number of protons and neutrons determine the nuclide.ne mole of atoms of any element always has the same number of atoms (about 7023602200000000000♠6.022×1023). This number was chosen so that if an element has an atomic mass of 1 u, a mole of atoms of that element has a mass close to one gram.

Atomic Number and Mass Number Atoms of the same element can have different numbers of neutrons. These atoms with the same number of protons, but different numbers of neutrons, are called isotopes. Think of isotopes like siblings - they are related, but have some differences. For example, all carbon isotopes have the same number of protons: six.

Periodic table of elements Elements in a group (column) have the same number of outer electrons, so they have similar chemical properties. There is an obvious pattern to look for: Atomic number increases as you move right along a row. Atomic number increases as you move down a column.

Isotope The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively.hus different isotopes of a given element all have the same number of electrons and share a similar electronic structure. Because the chemical behavior of an atom is largely determined by its electronic structure, different isotopes exhibit nearly identical chemical behavior.

Chemical element The mass number of an element, A, is the number of nucleons (protons and neutrons) in the atomic nucleus. Different isotopes of a given element are distinguished by their mass numbers, which are conventionally written as a superscript on the left hand side of the atomic symbol (e.g., 238 U).he atomic number of an element is equal to the number of protons in each atom, and defines the element. For example, all carbon atoms contain 6 protons in their atomic nucleus; so the atomic number of carbon is 6.

Chemical element Isotopes are atoms of the same element (that is, with the same number of protons in their atomic nucleus), but having different numbers of neutrons. Most (66 of 94) naturally occurring elements have more than one stable isotope. Thus, for example, there are three main isotopes of carbon.

- Chemical elements contains 11 transuranic actinide elements, with atomic numbers ranging from 93 to 103. An element is defined by its atomic number, the number of protons in the atomic nucleus. Nuclei with the same atomic number but different numbers of neutrons are isotopes of the same element.H TRU has a surface dose rate not greater than 2 mSv per hour (200 mrem /h), whereas RH TRU has rates of 2 mSv/h or higher. CH TRU has neither the high radioactivity of high level waste, nor its high heat generation.

Atoms In all atoms, the number of protons and the number of electrons is always the same. The number of neutrons is very roughly the same as the number of protons, but sometimes it's rather more. The number of protons in an atom is called the atomic number and it tells you what type of atom you have.

The atomic number also tells you the number of _________ in a neutral atom of that element. Please help!I'm really confused. There is a one to one ration between the number of protons and the number of electrons. An atom that has 6 protons also has 6 electrons. The only way this balance can change is if the atom loses or gains electrons; then the atom is called an ion, which is a charged atom.

- The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1.xygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.

Saxophone Buyer's Guide The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.
