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
Based on this, the two elements would be barium and radium.
