Nitrogen has the atomic number 7, the atomic symbol N, and it is a gas at room temperature. It exists in two stable isotopes, with the most common isotope having a mass number of 15. Nitrogen is used in fertilizers, as well as in explosives, and it can be used as an anesthetic in...
Thus, the atomic number of the element is 7. Step 5: Identify the ElementThe element with atomic number 7 is Nitrogen (N). Step 6: Determine the GroupNitrogen belongs to the p-block of the periodic table. To find the group number for p-block elements, we can use the formula:- Group...

Nitrogen is a chemical element with a symbol N and atomic number 7. Know here all about Nitrogen cycle, properties, uses, formula, symbol, fixation, etc.
Protons have a relative mass of 1, which is the same as the relative mass of neutrons. The number of protons in an atom is called the 'Atomic Number' of that atom and is sometimes referred to as 'Z'. This is important because it defines the type of atom, i.e. which element it ...
Atomic Mass of Iron An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...

that would otherwise push the protons apart, according to the rules of electricity. Some atomic nuclei are unstable because the binding force varies for different atoms based on the size of the nucleus. These atoms will then decay into other elements, such as carbon-14 decaying into nitrogen-...
That is ,as the elements increase in atomic number (number of protons in their nucleus) , every so often and element appears that is similar in its properties to one that has occurred early in the table. For example, after lithium, with three protons in its nuclei, come after the ...
