Number of neutrons = Mass number - atomic number
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
Lithiums in the group Alkali metals
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 is number of protons in an atom, plus the number of neutrons.
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
Lithium is sometimes called "the magic ion" or "the light metal" due to its properties and uses in various applications, including rechargeable batteries and mood-stabilizing medication.
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
To find the mass number of an element, add together the number of protons and neutrons in the nucleus of an atom. The mass number is typically written as a superscript to the left of the element symbol.
To find the number of neutrons from the mass number, subtract the atomic number from the mass number. The atomic number represents the number of protons in an atom, and by subtracting it from the mass number, you can determine the number of neutrons present.
