2) suppose you discovered a new element with 120 protons and 2 electrons in its outermost energy level (valence shell).

a. in which group does this new element belong?

b. is this new element a metal, a nonmetal, or a metalloid? explain your reasoning.

a. Group 2

b. Metal

a. The current highest numbered element known is Oganesson with an atomic number of 118 and it's the last period 7 element in group 18 (Noble gases). The hypothetical element number 120, would be the 2nd element in period 8 and the described electron configuration matches other group 2 elements such as Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.

b. The hypothetical element would be quite similar to the other group 2 elements which are the alkaline earth metals. The element would be expected to be a bit more reactive than Radium.
