common factor
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors.
A number with the same last and middle numbers is called a palindrome. Palindromic numbers read the same forwards and backwards.
Isotopes are atoms of the same element with the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
Isotopes are atoms with the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers.
common factor
Atoms containing the same number of protons but different numbers of neutrons are called isotopes. Isotopes have the same atomic number (number of protons) but differ in atomic mass due to the varying number of neutrons.
Isotopes
It is a sequence of numbers which is called an arithmetic, or linear, sequence.
They are called common factors when they are the same for two or more numbers. They are factors that are common to both number.
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
