A new element, element Tj, is discovered on a separate planet. The energy required to ionize one mole of Tj atoms is about 1600 kJ per mole. what frequency should 1 mole of photons have in order to ionize 1 mole of Tj atoms?​

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.

its b it was a compound

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.
