The answer for the question is C
The element group which is least likely to form ions is 4A group
<u><em>explanation</em></u>
Element of group 4A has 4 valence electrons. for example Carbon which has [He] 2S2 2P2 electron configuration has 4 valence electrons.
Since 4A elements has 4 valence electrons , it means that their valence shell is half filled which is relatively stable. <em>For this reason 4A element readily form ions.</em>
Answer:
3 valence electrons
Explanation:
Aluminum has three valence electrons. Valence electrons are found in the outermost shell of an element and are responsible for its valence.
Answer:
Bond angle is affected by the presence or addition of lone pair of electrons at the central atom. Due to this, the bonds are displaced slightly inside resulting in a decrease of bond angle, and when you remove an electron domain the bond angle increases.
