Copper II oxide is a compound.
3.2 x10000000
the correct answer is 3.2x 10⁷
- Nitrogen as in NH₃.
- Phosphorous as in PH₃.
<h3>Explanation</h3>
Hydrogen is in group 1. It is one electron away from the next noble gas element. It would form one single covalent bond when it bonds to nonmetals.
A nonmetal atom will gain three extra electrons when it bonds to three hydrogen atoms. For the molecule to be stable, that nonmetal atom should be three electrons away from the next noble gas element. Each of the atoms in question should contain 8 - 3 = 5 valence electrons when neutral. Which column on a periodic table contains such elements?
Explanation:
Hybridization of 
is 
Bond pair in = 2
lone pair in = 2
Because of presence of two lone pairs of electron shape is bent.
F is more electronegative than O, therefore two O-F bons are polar and hence, two dipole exists. The resultant diople moment in a molecule is the vector sum of individual existing dipoles (shown in the attachment).
because of the bent shape of two dipole moments add to each other. this result in the existence of permanent dipole moment in the molecule and thus is a polar molecule.
