An atom of lithium-7 has an equal number of  (1) electrons and neutrons  (2) electrons and protons  (3) positrons and neutrons  (4) positrons and protons 2015-06-01T18:03:41-04:00. The answer is (2). The Lithium has 3 protons and 4 neutrons. For every neutral atom, it will have the same number of protons and electrons. Because the proton has one positive charge and electron has one negative charge and neutron does not have charge. Comments

How many protons, neutrons, and electrons does lithium have? Lithium always has 3 protons: its atomic number is 3, and this is decided BY its amount of protons (or by its nucleus' charge if you want to get more technical). Therefore, a lithium atom with neutral charge will have 3 electrons, too. 92.5% of naturally occurring lithium atoms are Li7, which has 4 neutrons. The only other stable isotope of lithium is Li6, which has 3 neutrons. This makes up for most of the rest of natural occurring lithium.

How Many Protons, Neutrons, and Electrons Are in an Atom? Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. The periodic table is arranged in order of increasing atomic number, so the number of protons is the element number. For hydrogen, the number of protons is 1. For zinc, the number of protons is 30.

2.6 Arrangements of Electrons The 1 s subshell cannot hold 3 electrons (because an s subshell can hold a maximum of 2 electrons), so the electron configuration for a lithium atom cannot be 1 s. Two of the lithium electrons can fit into the 1 s subshell, but the third electron must go into the second shell.The second shell has two subshells, s and p, which fill with electrons in that order. The 2 s subshell holds a maximum of 2 electrons, and the 2 p subshell holds a maximum of 6 electrons.Because lithium’s final electron goes into the 2 s subshell, we write the electron configuration of a lithium atom as 1 s 2 s.he 2 s subshell holds a maximum of 2 electrons, and the 2 p subshell holds a maximum of 6 electrons. Because lithium’s final electron goes into the 2 s subshell, we write the electron configuration of a lithium atom as 1 s 2 s.

How many neutrons protons and electrons does lithium have? In Lithium-5, The number five indicates the mass number or weight in amu's. This is a sum of both the proton and neutrons in an atom. Since Lithium always has 3 protons(… otherwise it would be a different element), it can be deduce that it has only 2 neutrons.

- There are 26 protons, 30 neutrons, and 26 electrons. To find the  protons, look at the periodic table. Iron (Fe) has an atomic number  of 26, so that's also how many protons … it has. Since it is not an  ion, it has to have the same number of electrons as protons, so  there are also 26 electrons.

- Lithium's electron configuration is 1s22s1, therefore lithium atoms have one valence electron in their outermost 2s sublevel.

How many protons, neutrons, and electrons does hydrogen have? Hydrogen can have any number of neutrons and still be hydrogen. H-1 (0 neutrons) is the most abundant isotope in nature. H-2 (1 neutron) has the special name of deuterium and is stable and found in nature. H-3 (2 neutrons) has the special name of tritium and is radioactive and very rare in nature, but has many applications as a synthetic product.

- Normally, lithium will lose one electron as an ion. Lithium is a metal, and because of this, will lose electrons instead of gaining them when forming an ion. Lithium only has … one outer valence electron in its outer energy shell which it easily looses when reacting with nonmetals (which gain electrons when conjoining with metals).

How many protons, electrons, neutrons does an Mg2+ion have? So the number of protons in magnesium is 12. Now since its given as Mg2+ ion. So you have to remove two electrons from magnesium. Magnesium has 12 electrons, now remove 2 and you get 10 electrons. so the number of electrons is 10 For the number of neutrons you need the atomic mass of magnesium, which is 24.

Ions and Ionization - How it works In certain situations, however, the atom may lose or gain one or more electrons and acquire a net charge, becoming an ion. Aluminum, for instance, has an atomic number of 13, which tells us that an aluminum atom will have 13 protons. Given the fact that every proton has a positive charge, and that most atoms tend to be neutral in charge, this means that there are usually 13 electrons, with a negative charge, present in an atom of aluminum.

- The nucleus of the helium atom contains 2 massive, positively charged particles. Thus, Z, the atomic number = 2. Z is simply the number of protons, massive, positively charged particles, present within the nucleus. Z thus defines the identity of the element: Z=1, hydrogen; Z=2, helium; Z=3, lithium;.................Z=80, mercury. You do not have to remember these numbers, because in every exam you ever sit you should be provided a copy of the Periodic Table, which lists all the elements in order of atomic number.

What charge does a lithium ion have? You define charge as the deficiency of electron in an atom. Lithium has 3 electrons, 2 in inner shell and 1 in outer shell. If lithium loses one electron then it is said to have a charge of +1 if 2 electrons lost then the charge would be +2 and if all the electrons are lost then charge would be +3. It is easier for lithium to lose one electron (outermost one) because of some factors (ionisation enthalpy, penetration power, outermost shell complete* etc).

How Many Protons, Neutrons and Electrons Does Sodium Have? Quick Answer. The element sodium has 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element's atomic number, which is also 11. The number of neutrons can be found by subtracting the atomic number from sodium's atomic mass of 23.

How many protons, neutrons, and electrons does beryllium have? Beryllium (Be) has an atomic number of 4. This means it is the fourth lightest element, and 4th in the periodic table. More importantly, this means it has 4 protons in the nucleus. Now, its atomic weight is 9. The weight of any atom is, roughly speaking, the sum of the number of protons and neutrons in the nucleus.
