The atomic number of sodium (na) is 11. the element phosphorous (p) is the fourth element to the right of sodium in the periodic table. the atomic number of phosphorus is it has zero charge because it has electrons.

Explanation:

Atomic number is the total number of protons present in an element or atom. When an atom is neutral then it contains equal number of protons and electrons.

For example, there are 15 protons in a phosphorous atom that is, atomic number of phosphorous is 15.

Also, it is known that an atom has zero charge when it is neutral in nature.

Hence, we can conclude that the atomic number of phosphorus is 15. It has zero charge because it has same number of protons and electrons.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
