Front

What is the name of the scientist who proposed the Bohr model of the atom?

Back

Bohr

Front

What is the principle quantum number represented by (n)?

Back

It indicates the energy level of an electron in an atom.

Front

How many sublevels are present in energy level 3?

Back

3 sublevels.

Front

What are the types of sublevels in energy level 3?

Back

s, p, and d sublevels.

Front

How many orbitals are there in energy level 3?

Back

9 orbitals.

Front

What is the maximum number of electrons that can occupy energy level 3?

Back

18 electrons.

Front

How many orbitals does the S sublevel have?

Back

1 orbital.

Front

What is the maximum number of electrons that can occupy the S sublevel?

Back

2 electrons.

Front

What is the first ionization energy?

Back

The energy required to remove the outermost electron from a neutral atom.

Front

Why does the first ionization energy require the most energy?

Back

As you remove electrons, the atom gets smaller since there are fewer repelling electrons.
