Answer:
the atom is unreactive due to the completely filled electron configuration so the atom with the seven valence cannot involved in it
C. Formation of a new substance
A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms. Since electrons spend more time with the oxygen atom, it carries a partial negative charge.
Answer:
They represent the valence electrons, so s and p sublevels only! This does not include the d block!
