Why do the elements in group IIA have very low electron affinities?

Elements combines to each other to form compounds eg: eg: Sodium (Na) combines with Chloride (Cl) and form new compound sodium chloride (NaCl). They do so w. r. t. certain...

Most of the times we come across elements which have symbols which are close to their English Names. But sometimes,an element is denoted by its Latin name instead of its...

The main reason the noble gases do not need to bond with other is that their outermost subshells are filled. These are known as . Take helium for example. It...

Organic substances have a relatively low polarity and generally have weaker intermolecular forces to hold them together tightly.

because group II is metals, and metals normally try to lose electrons to become metal cations, and as you go down a group the nucleus has a less strong hold...

The realization that earths were in fact oxides was attributed to Lavoisier. And the Group 2 metals form a stable series of sparingly soluble binary oxides. I am told that...

The electro negativity of the in group II A goes down as the goes up. The further down the atoms are in the periodic table the lower the attraction for...

This is because all of the Noble Gases have complete valence electron shells. They have a complete set of 8 electrons. Think of 8 as being the best car...

in group $14$ have $4$ . Meaning that to achieve a stable octet they need to either gain or lose $4$ electrons in total. That would take significantly more...

By transferring one of the s electrons to a d orbital the d orbitals become completely filled. Not only is the d orbital filled all of the orbitals in the...
