Interpretation Introduction

Interpretation:

The element containing 14 protons needs to be identified.

Concept introduction:

The number of protons is equal to the atomic number of an atom which identifies the atom of a particular element.

Answer to Problem 14PP

The element with 14 protons in its atom is Silicon.

Explanation of Solution

Number of protons is equal to the atomic number. So, in the modern periodic table, the element that has atomic number 14 is Silicon. It is represented by symbol Si and is a member of group 14 in the periodic table. Silicon is a hard, brittle and crystalline solid. It has blue-grey metallic luster and is a tetravalent metalloid. Silicon acts as a semiconductor.

Conclusion

The chemical element Silicon (Si) has 14 protons in its atom.
