Hi any one is on now​

Which three statements represent the benefits of performing experiments using computer simulations?

Question 3(multiple choice worth 4 points) (04.04 lc) what does it mean when an element is reduced? it empties a valance shell, reducing its atomic radius. it gains electrons, reducing its overall charge. it increases electronegativity, reducing its ability to bond. it loses electrons, reducing its electron number.

How many neutrons does an element have if its atomic number is 50 and its mass number is 166
