Answer:

<em>A</em>. Arsenic

Explanation:

Arsenic is a metalloid. Arsenic has properties of both metals and non-metals that is why it is a metalloid.

Potassium, chlorine, and indium do not have both properties of metals and non-metals, therefore they are not metalloids.

A hydrogen atom in an excited state can be ionized with less energy than when it is in its ground state. What is n for a hydroge
Molodets [167]

Explanation:

It is known that formula for the ionization energy of hydrogen atom is as follows.

               E = \frac{13.6 eV}{n^{2}}

or,          n = \sqrt{\frac{13.6}{E}}

The value of energy is given as 0.544 eV. Therefore, we will calculate the value of n as follows.

                   n = \sqrt{\frac{13.6}{E}}

                      = \sqrt{\frac{13.6}{0.544 eV}}

                      = 5

Thus, we can conclude that n equals to 5 for a hydrogen atom if 0.544 eV of energy can ionize it.
