An element is made up of a) one type of atom b)more than two types of atoms

B) more than two types.

Explanation:

I believe there about 109 different atoms in one single element.

Hope this helps !!

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
