In the human body, Nitrogen is the the fourth most abundant element accounting for 3% of its total mass. Moreover, it is estimated as the seventh most commmon element in the Milky Way and the Solar System. Nitrogen is a nonmetallic chemical element represented by the symbol N. It is ...
What is the symbol for the isotope with 80 protons and a mass number of 202? How many neutrons does it have?Mass Number:The mass number of an atom represents the number of nucleons in the nucleus of an atom. Nucleons is a general term for ...
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
What is a molecule? A molecule is two or moreatomsconnected by chemical bonds, which form the smallest unit of a substance that retains the composition and properties of that substance. Molecules form the basis of chemistry. Molecules are noted with theelementsymbol and a subscript with the num...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
Add one proton, one neutron, and one electron and you get an atom of beryllium (symbol Be).See how it works? In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and...
