the molarity of water is 55.5.
No. H2 does not have a permanent dipole moment.
The ending of the second element is changed to -ide
Ions combine in only one ratio, so prefixes are not needed.
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs.
So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
subtract the group number from the atomic number
If the electronegativity difference between two atoms is below 1.7, then the two atoms form covalent bond.
Cl -apex.
The valence electrons.

Dipole-dipole forces play a significant role when a molecule is polar.
put parentheses around the atoms in the ion and then add a subscript - apex
