There are 10 neutrons for each F atom, and 5 for each Be atom, so each BeF2 molecule will have
10+10+5=15 neutrons.
You need 3 molecules, so
3*15=45
No, BeF2 does not have a 3 charge. Beryllium fluoride (BeF2) is a neutral compound with a 2+ charge on the beryllium ion and a 1- charge on each fluoride ion, resulting in a net charge of 0.
An atom is primarily composed of three subatomic particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus. These molecules are responsible for the structure, stability, and properties of an atom.
Lithium has 3 protons and typically 4 neutrons in its nucleus.
