The mass number is the sum of the neutrons and protons which exist in the atomic nucleus of an isotope.
You get the number of neutrons in the atom. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Subtracting the atomic number from the mass number gives you the number of neutrons because the difference accounts for the protons.
The mass number represents the weight of the protons and neutrons in Atomic Mass units (AMUs). One AMU is equal to one proton or neutron.The average mass of all isotopes of the element - apex.
The mass number of lithium is 7. This number represents the total number of protons and neutrons in the nucleus of a lithium atom.
An atom of sodium with an atomic number of 11 and mass number of 24 is 2411Na.
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
The mass number
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
The mass number is sum of neutrons and protons in the atomic nucleus.
This is the mass number.
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
It represents the atomic number and atomic mass. Mass number is the superscript Atomic number is the subscript
You get the number of neutrons in the atom. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Subtracting the atomic number from the mass number gives you the number of neutrons because the difference accounts for the protons.
mass number
The mass number represents the total number of protons and neutrons in an atom's nucleus. It determines the isotope of an element. The atomic number represents the number of protons in an atom's nucleus, defining the element and its unique properties on the periodic table.
The mass number of gold is 197. This number represents the total number of protons and neutrons in the nucleus of a gold atom.
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
The mass number for carbon is 12, which represents the total number of protons and neutrons in the nucleus of a carbon atom.
