Want this question answered?
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.
completely filled valence shells
Electrons called valence electrons are most likely removed. These are the outermost energy level electrons.
With only 1 electron in its valence shell, the atom is likely to form an Ionic bond.
It's a noble gas with a full outer shell of valence electron. It is naturally averse to losing any of them.
lose an electron and become a positive ion.
This atom lose an electron.

it would be probably 2-.
Positive 1 charge
K+ So it loses one electron
Group one elements have one valence electron. In order to achieve a "happy" electron configuration, they try to lose this valence electron. Electrons have a negative charge, so once they lose this electron, they have a +1 charge.

filled energy sublevels
If an atom has three electrons, it will have one valence electron (valance = outer shell). It will be more likely to lose an electron than gain one, since it has only one to lose, but seven to gain.
