Atoms
Explanation:
Chemical bonds results from the rearrangement of atoms in a chemical species.
It deals with the various attractive forces joining chemical species togethe.
- When atoms are re-arranged, they form chemical bonds that leads to production of new compounds.
- This is made possible by the exchange or sharing of electrons.
- The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
- When atoms are re-arranged in compounds they lead to the production of chemical bonds.

Answer:
The high system pressure and relatively large chlorine molecule size.
Explanation:
Having the expression of the ideal gas, and clearing the pressure, we have:
P = nRT/V
Meanwhile, for a non-ideal gas we have the following equation:
P = (nRT / V-nb) - n2a/V2
In this equation, high pressures and low temperatures have an influence on nonideal gases.
Therefore, at high pressures, the molecules in a gas are closer together and have high intermolecular forces. On the other hand, at low temperatures, the kinetic energy of a gas is reduced, so that the intermolecular attractive forces are also reduced.
Answer:B. The sodium ion has a smaller radius than the atom.
Explanation:
Because size of cation is less than neutral atom
