To have a complete outermost shell, the sodium atom would: * a-gain 7 electrons forming sodium atom
b-lose an electron forming sodium atom
c-gain 7 electrons forming sodium ion
d-lose an electron forming sodium ion

Sodium (Na) is an alkali metal which is very reactive, having only one valence electron.

in order to attain stability or to complete octet, he donates or loses its outermost electron.

after losing an electron Sodium forms a Cation ( positive ion ) due to more protons in atom as compared to electrons.

hence; the correct option will be...

D -lose an electron forming sodium ion

hi,

the answer is d.indefinite shape but definite volume, let go oogle u out

hope this !
