Number of neutrons = Mass number - atomic number
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
The mass number of deuterium is 2
Lithiums in the group Alkali metals
lithium s atomic no is 3 it has 3 protons and 3 electrons
Li is atom number three, not only 'was' but it still is and ever will be.
Li
Li,lithium, and li
alkaly metals
At STP (Standard temperature and pressure) lithium is a solid.
If you think to the boiling point (not burning point) this temperature is 1342 0C.
Lithium is a metal element. There are 3 electrons in a single atom.
yes mass can be a number
Number of neutrons = Mass number - atomic number
The formula for mass number is number of neutrons = mass number - atomic number. Mass number can also be referred to as nucleon number.
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
