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 the mass of the atom. (I need help.)

Answer 1

the mass would be 7 because the sum of neutrons and protons so 4+3=7
the charge would be neutral because theres an equal number of electrons and protons
the structure is determined by using the periodic table so because this element has 3 protons you look at the atomic number and the only element on the periodic table with an atomic number of 3 is lithium :)

Answer 2

this is the lewis diagram for Li and it shows you how the shells would be arranged
