One neutral atom of nitrogen has seven protons, seven neutrons and seven electrons. This element is found in group 15 and period 2 of the Periodic Table of the Elements. It has an atomic weight of 14.007 amu.Know More
Nitrogen is the seventh element on the periodic table. It has an atomic number of 7, so it also has seven protons. Because nitrogen has an atomic weight of 14.007 amu, its mass number is 14. Subtracting the number of protons (7) from the element's mass number (14) makes it possible to determine the number of neutrons in the atom.
Many nitrogen atoms have seven neutrons (14-7 = 7). Some atoms of nitrogen, however, have eight electrons. They are atoms of N-15, an isotope of nitrogen.
In a neutral atom, the number of protons must equal the number of electrons. This means a neutral atom of nitrogen must have seven electrons to match its seven protons.Learn more about Atoms & Molecules
There is a potential maximum of 50 electrons in the fifth energy level of an atom. The formula for determining the maximum number of electrons in any energy level is two times n squared, where n is the energy level.Full Answer >
A valence electron is a type of electron present in an atom that works to aid in the process of chemical bond formation with other atoms. These electrons are present in the outer shell of an atom.Full Answer >
An electron is a negatively charged sub-atomic particle that is located in an atom along with protons and neutrons. The electrons are found in shells and sub-orbitals that surround the nucleus of the atom.Full Answer >
