The elements are the arranged in the periodic table in order of increasing atomic number.

<h3>What are the elements?</h3>

The elements are the arranged in the periodic table in order of increasing atomic number. We know that the atomic number refers to the number of protons in the atom. The sum of the number o protons and the number of neutrons in the atom gives the mass number of the atom.

In the case of the first element, there are 7 neutrons and the mass number is 15. Thus the number of protons = 15 - 7 = 8. The element that has atomic number 8 is oxygen (O).

In the second case, the atomic number is 26 is iron. Given that the mass number is 56, there are 30 neutrons and the element symbol is Fe.
