They form sodium chloride, a chemical compound; the formula unit is NaCl. This is not a true molecule because ionic compounds forms large lattices.
triple bonding
NaCl is an example of ionic bonding. Sodium (Na) donates an electron to chlorine (Cl), forming positively charged sodium ion and negatively charged chlorine ion that are held together by electrostatic forces.
Three bonding pairs, thus a pyramid.
In BF3, there are 3 bonding electron pairs and 0 non-bonding electron pairs. Boron has 3 valence electrons, and each fluorine contributes one electron for bonding, giving a total of 3 bonding pairs in the molecule.
Oxygen has two non-bonding pairs of electrons.

In phosphine (PH3), there are three lone pairs and three bonding pairs.
Repulsion between lone pairs is stronger because they are closer to the nucleus and repel more strongly than bonding pairs. Lone pairs have less electron-cloud shielding compared to bonding pairs, resulting in increased repulsion. This leads to lone pairs pushing each other apart more forcefully than bonding pairs do.
3 and SO3 is an anion with a +1 charge
Ionic bonding. Salt, NaCl, contains Na+ and Cl- ions.
Lone pairs reduce bond angles because they occupy more space than bonding pairs of electrons. This increased repulsion from the lone pairs pushes the bonding pairs closer together, resulting in smaller bond angles. Additionally, lone pairs are not involved in bonding interactions, so they exert a stronger repulsive force on adjacent bonding pairs, further distorting the geometry of the molecule.
