What happens to the size of an atom if it loses an electron?
What happens to the size of an atom if it loses an electron?
The loss of an electron means that there are now more protons than electrons in the atom, which is stated above. This will cause a decrease in atomic size because there are now fewer electrons for the protons to pull towards the nucleus and will result in a stronger pull of the electrons towards the nucleus.
What forms after an atom loses electrons?
An atom loses electrons to form a cation , that is a positively charged ion (and one that is attracted towards the negatively charged terminal, the cathode ). Both charge and mass have been conserved.
What happens when you lose electrons?
Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
Do all atoms lose electrons?
The atom then loses or gains a “negative” charge. These atoms are then called ions. Positive Ion – Occurs when an atom loses an electron (negative charge) it has more protons than electrons…….How do atoms lose and gain electrons?
| Here are some examples of common ions: | |
|---|---|
| Na+ | Sodium |
| P- | Phosphorous |

Why do atoms generally become smaller as one?
4 Answers. As you move from left to right across a period, the number of protons in the nucleus increases. The electrons are thus attracted to the nucleus more strongly, and the atomic radius is smaller (this attraction is much stronger than the relatively weak repulsion between electrons). As you move down a column, there are more protons,…
Why does the radius of an atom increase as you move down a column?
As you move down a column, there are more protons, but there are also more complete energy levels below the valence electrons. These lower energy levels shield the valence electrons from the attractive effects of the atom’s nucleus, so the atomic radius gets larger.
How does oxidation affect the radius of an atom?
And thus oxidation should reduce the atomic radius (i.e. the ionic radius is reduced with respect to the parent atom): And reduction should INCREASE the radius with respect to the parent atom. This is good illustration that illustrates this principle:
