What determines the chemical reactivity of an atom?

Back

Chemical reactivity is determined by the electrons, particularly the valence electrons.

Front

How do you calculate the mass number of an atom?

Back

The mass number is calculated by adding the number of protons and neutrons in the nucleus.

Front

What is the mass number of an atom with 10 protons and 15 neutrons?

Back

The mass number is 25 (10 protons + 15 neutrons).

Front

What are the four types of sublevels in atomic structure?

Back

The four types of sublevels are s, p, d, and f.
