Name two elements that would have properties similar to beryllium, with atomic weights higher than 130.

two elements would be barium and radium.

Explanation:

in the periodic table, elements of the same group are characterized by having the same similar properties.

So, first we will check the elements that lie within the same group as beryllium  and then we will attempt to choose the elements with atomic mass higher than 130.

So, elements in the same group as beryllium are: magnesium, calcium, strontium, barium and radium.

Among these elements, we will find that:

radium has atomic mass of 226 amu

barium has atomic mass of 137.327 amu

the answer is c.the valence of the atoms combine .
