Atomic mass is never an integer number for several reasons: The atomic mass reported on a periodic table is the weighted average of all the naturally occuring isotopes. Being an average it would be most unlikely to be a whole number. The mass of an individual atom in atomic mass units is the mass relative to carbon-12.
Q. Why is Ram of chlorine not a whole number?
Answer: The reason for the atomic mass of chlorine taken as 35.5u and not as 35u because of the presence of isotopes. Isotopes are defined as variants of a particular element where these variants will have the same number of protons but differ in the number of neutrons in the atom.

Q. What is the difference between two isotopes?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
Q. Why silicon has no overall charge?
Although the atom is built from oppositely charged particles, its overall charge is neutral because it contains an equal number of positive protons and negative electrons.
Q. Why does magnesium atom have no overall charge?
Magnesium has two electrons in its outer shell as it is in group 2 of the periodic table, which it loses, so its outer shell is full (2,8) and it has a charge of +2, as it still has 12 protons (positive charges) and now has only 10 electrons (negative charges).
Q. Why does a magnesium ion has a charge of 2+?
Explanation: Magnesium is under group 2 that also has a valence electron of 2. To achieve stability and to follow the octet rule, these 2 electrons in the outer shell will be removed making this atom into an ion with a 2+ charge.
Q. What is the atomic charge of magnesium?
12
Q. Does magnesium have a zero charge?
In a neutral atom, the number of protons, which is given by the element’s atomic number, is equal to the number of electrons. So, for instance, you have a neutral magnesium atom ( Mg ). Magnesium has an atomic number of 12 . Twelve protons, or twelve +1 charges, and twelve electrons, or twelve -1 charges.
Q. Is MGO neutral?
Answer. ……………. Magnesium is a metal and like most of the metals, it form basic oxides. Since magnesium oxide accepts protons (H^+ ions), it is a .
Q. Does magnesium have a positive charge?
A magnesium ion has a net positive charge while the magnesium atom has no charge.
