What is this element

Oxygen

Explanation:

From the question given above, the following data were obtained:

Number of electrons = 8

Number of protons = 8

Number of Neutrons = 8

Name of element =?

Next, we shall determine the atomic number of the element. This can be obtained as follow:

The atomic number of an element is simply defined as the number of protons in the atom of the element. Mathematically, it is expressed as:

Atomic number = proton number

From the question given above,

Number of protons = 8

Therefore,

Atomic number = 8

Comparing the atomic number of the element (i.e 8) with those in the periodic table, we can conclude that the element is oxygen since no two elements have the same atomic number.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
