Question

A given atom has 3 protons, 4 neutrons, and 3 electrons. Describe how you can use those three values to describe the structure, charge, and mass of the atom.

Answer 1

The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. In this case, the atomic number of the atom is 3 and the atomic mass is 7. Hence the element is Lithium, a metal
