Covalent bonds usually occur between atoms that have
marta [7]

Answer: A: high ionization energies; high electron affinitlies.

Explanation: Covalent bonds are basically about sharing of electrons between two atoms to achieve that stable structure. They are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or fairly similar ionization energies and electron affinities). Covalent bonding usually occurs between two non-metals.

For effective and proper bonding, the two atoms involved in the covalent bonding exercise should be small and hungry for electrons. This is to enable the nuclei of both atoms to effectively attract and hold the shared electron(s) in place; hence, the need for high ionization energies & high electron affinities for a more effective covalent bonding.

Which of the following is NOT part of the kinetic molecular theory of gases?
kondaur [170]

A. There is very little empty space in a gas in not part of the kinetic molecular theory of gases.

Explanation:

The kinetic molecular theory of gases follows following points:

Kinetic energy does not change or get dissipated when gas molecules collide with each other. No attraction or repulsion between gas particles is observed. Particles of  gas are moving randomly in all directions. Temperature increase cause the rapid movement of gas particles.The gas particles are placed very far from each other as compared to liquid.

The empty space in a gas is large because gas gets compressed in the small volume of the container also.
