<u>Answer:</u> The element is Fluorine.

<u>Explanation:</u>

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Atomic mass is defined as the sum of number of protons and neutrons that are present in an atom.

Atomic mass = Number of protons + Number of neutrons

We are given:

Number of protons = 9 = Atomic number

Number of electrons = 9

Number of neutrons = 10

Mass number = 9 + 10 = 19

The element having atomic number equal to 9 and mass number equal to 19 is fluorine.

Hence, the element is Fluorine.

The correct answer is C.  We know this is true since the number of protons an atom has is its atomic number.  Since this atom  has 9 protons, look for the element on the periodic table that has an atomic number of 9.  The element that has an atomic number of 9 is flouring.

I hope this helps.

S_A_V [24]

A type of atom can be of any type. Elements are pure chemicals that cannot be converted into more basic compounds by conventional chemical processes.

A chemical element is a substance that cannot be disassembled chemically or physically into simpler substances. Chemical elements are the basic building blocks of matter because they are pure substances made up of atoms with the same atomic number (number of protons) in their nuclei. A chemical element is essentially a pure substance that cannot be disintegrated, degraded, or changed into other compounds through physical or chemical methods.
