Answer is Nitrogen, atomic number 7
The atomic number of nitrogen is 7. Hence, the number of electrons in the nitrogen atom is 7. In the nitrogen, valance electrons are 3 in number in 2P orbital. Its valency is 3. Therefore, it can make three bonds with other elements which is highest among the given options.

Thus, option D) is the right answer.
Image result for In what ways do cells use energy
Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.
No but they are considered protected
