Question

Answer choices : Calcium, Argon, Sodium, Nitrogen, Oxygen, Chlorine

Answer 1

Zero D.

SODIUM is the element which would become stable by losing an electron.

It becomes an ION in its IONIZATION.

As SODIUM loses 1 electron, it is left with (11) protons & (10) electrons.

Hydrogen & lithium are also in Group -1 elements with SODIUM. This means these elements have 1 electron in the outermost shell.

.These elements are unstable as a single atom.
