How many protons neutrons and electrons are in chlorine? There are 17 protons in the nucleus of each chlorine atom. The number of neutrons is different for different isotopes of chlorine, but is always the difference between the iso … topic mass number and the atomic number, which is the same as the number of protons in each nucleus.

- The pair of shared electrons between the chlorine and hydrogen atoms form a single covalent bond. The structural formula of a hydrogen chloride molecule is written. There are no ions present (no + or-charges) in hydrogen chloride gas because the electrons are shared, not transferred from one atom to another. hydrogen atom has 1 electron in its outer shell. Hydrogen can only form 1 bond. The hydrogen atom will share its 1 electron with chlorine to form one covalent bond and make a hydrogen chloride molecule (HCl).

How Many Electrons Does Chlorine Have? An atom of chlorine has 17 electrons. These electrons are negatively charged and are arranged in orbits around the nucleus of the chlorine atom. The nucleus has 17 positively charged protons. The electronic configuration of the chlorine atom is 2, 8, 7; this means that the first orbit has a complete set of two electrons, the second orbit has a complete set of eight electrons, and the third orbit has an incomplete set of seven electrons. The chlorine atom needs one more electron to complete this orbit with eight electrons. This gives chlorine a valence of 1 for chemical reactivity. The atomic number of chlorine is 17.

- Negative ions are bigger than the atoms they come from. Chlorine is 2,8,7; Cl- is 2,8,8. Although the electrons are still all in the 3-level, the extra repulsion produced by the incoming electron causes the atom to expand. There are still only 17 protons, but they are now having to hold 18 electrons.

Molecular Structure The Reaction between Sodium and Chlorine. Chlorine has 7 electrons in its outer shell. It is in group 7 of the periodic table. When an atom of chlorine reacts it will gain one electron from. sodium. The outer shell of chlorine will then have 8 electrons. and be full. The chloride ion will have an extra electron. and therefore an extra negative charge (shown as a - sign).

- The first ionization energy for sodium is one and one-half times larger than the electron affinity for chlorine. Na: 1st IE = 495.8 kJ/mol. Cl: EA = 328.8 kJ/mol. Thus, it takes more energy to remove an electron from a neutral sodium atom than is given off when the electron is picked up by a neutral chlorine atom.

If Carbon-12 has 8 neutrons......what is the atomic number of carbon-14......? that isn't correct, carbon12 has 6 protons and 6 neutrons. The atomic number of any carbon isotope is 6 because they have 6 protons. I guess if you were imagining carbon12 had 8 neutrons, that would leave 4 protons giving an atomic number of 4 for carbon isotopes, but that's not how it is.

What Element Has 20 Protons and 20 Neutrons? Calcium's atomic weight of 40.078 rounds to a mass number of 40. Subtracting 20 from 40 yields a result of 20. This means an atom with 20 protons and 20 neutrons must be an atom of calcium. In some cases, calcium does not have 20 neutrons.

How many protons and electrons are in the atom of carbon? Report Abuse. 6 protons, 6 neutrons (in most favorable isotope) and 6 electrons. Carbon is # 6 on the periodic table, so it has 6 protons by convention of the periodic table. For a neutral atom the number of electrons always equals the number of protons.

How do we calculate for the Average Atomic Mass of an element? So for the chlorine example, where there are only two naturally occurring isotopes, you would use the following. 75.58 percent of chlorine atoms are chlorine-35 and 24.22 percent of chlorine atoms are chlorine-37. The average atomic mass = 0.7578 x 34.9689 + 0.2422 x 36.9659 = 35.453 amu.Source(s):pisgahchemist · 7 years ago.5.58 percent of chlorine atoms are chlorine-35 and 24.22 percent of chlorine atoms are chlorine-37.

What is the chemical symbol for the ion with 9 protons and 10 electrons??? The element with 9 protons and 9 electrons would be Fluorine. Since elements exist electrically neutral in their natural states, it would be impossible for an element to have more electrons than protons, or vice versa. What you may have meant, however, is 9 protons and 9 neutrons. Neutrons have no electrical charge, but do add weight.

Why does chlorine always have a relative atomic mass of about 35.5u? So, when the mass of chlorine is measured using an instrument called a mass spectrometer the result is a mass of 35.5. The atomic weight, or as it is properly called, the RELATIVE atomic mass, is a weighted average of the masses of all the isotopes of chlorine. Relative Atomic Mass = (75/100 x 35) + (25/100 x 37) = 35.5 Isotopes of any element behave the same chemically because neutrons do not have any charge.

- Key difference: Chlorine is a naturally occurring element with a symbol Cl and atomic number 17. Under standard conditions, the element is a yellow-green gas. Chloride is an ion of chlorine. Essentially, when atoms gain or lose electrons, they become ions. Chlorine atoms gain one electron to become a chloride ion (Cl −). An ion cannot remain in a free state, and has to combine with another element or elements to form a compound. Chlorine is a naturally occurring element with a symbol Cl and atomic number 17.

- Multiply the element's atomic mass by the molar mass constant by the number of atoms of that element in the compound. Here's how you do it: 1  For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.his is defined as 0.001 kilogram per mole, or 1 gram per mole. This converts atomic units to grams per mole, making the molar mass of hydrogen 1.007 grams per mole, of carbon 12.0107 grams per mole, of oxygen 15.9994 grams per mole and of chlorine 35.453 grams per mole. 3. Find the molar mass of a divalent molecule.

Molecular Structure Chlorine and hydrogen are both non-metals. A chlorine atom has 7 electrons in its outer shell. Chlorine is in group 7 of the periodic table. A hydrogen atom has 1 electron in its outer shell. Hydrogen can only form 1 bond. The hydrogen atom will share its 1 electron with chlorine to form one covalent bond and make a hydrogen chloride molecule (HCl). This is a picture of a hydrogen chloride molecule. By sharing the two electrons where the shells touch the hydrogen atom can count 2 electrons in its outer shell and the chlorine atom can count 8 electrons in its outer shell.

Proton number, neutron number and electron number in 81 Br-1? The atomic number, 35, is the number of protons (+ charge) in the nucleus. In order to be neutral, the number of electrons (- charge) must match the number of protons. The atomic mass, 79.9, is the average of bromine's 2 stable isotopes: Br-79 (50.69%) and Br-81 (49.31%). Let's just say it's 80.
