How is beryllium (Be) similar to calcium (Ca)?
A. Both are rare metals.
B. Both react readily with elements in Group 1.
C. Both are very reactive.
D. Both rarely combine with other elements.

Beryllium (Be) is similar to calcium (Ca) because both are somewhat reactive metals at standard temperature and pressure. Hence, option C is correct.

What is the alkaline earth metal group?

The alkaline earth metals are six chemical elements in group 2 of the periodic table.

They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

The second column on the periodic table of the chemical elements is collectively called the alkaline earth metal group: beryllium, magnesium, calcium, strontium, barium, and radium.

Because the outer electron structure in all of these elements is similar, they all have somewhat similar chemical and physical properties.

Beryllium (Be) is similar to calcium (Ca) because both are somewhat reactive metals at standard temperature and pressure.

Hence, option C is correct.
