what are atoms of same elements having Z But different A
Answers
Answer: This may help you
Explanation:
Atoms of the same element having same atomic number but different mass number (atomic mass/weight) are called isotopes.
An atom is the smallest particle of an element which can take part in chemical reaction. Atom consists of three fundamental particles i.e. proton, neutron and electron. Atoms of same elements are similar in properties whereas atoms of different elements are different in properties. Example:- ‘H’ represent the atom of hydrogen.
Atomic number :
Atomic number is the number of protons present in an atom.
The modern periodic table is arranged in order of increasing atomic number.
Mass number and Atomic mass :
Mass number is the sum of the number of protons and the number of neutrons present in an atom. It is a whole number.
Mass no. of an atom = No. of protons + No. of neutrons
Atomic mass is the average mass of the all of the isotopes of that element. It is a decimal number.
