You are prolly asking this for an online true/false test or something, but the answer is no, not necessarily. They do always have the same number of electrons and protons however.
The sum of protons and neutrons in an atom is called mass number.
Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons. Example: Calcium atom contains 20 protons and 20 neutrons. But some atoms contain same number of protons but different number of neutrons. For example carbon atoms exist in three forms - all contain 6 protons but some contain 6 neutrons, some 7 neutrons and others with 8 neutrons. These type of atoms are known as isotopes Definition of isotope: Atoms with same number of protons but different number of neutrons It shows that the different number of neutrons determines the existence of isotopes. Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons.

Atoms with more protons than neutrons are simply isotopes of an element. Atoms of an element always have the same number of protons. However, the number of neutrons can vary and can be higher, lower, or equal to the number of protons.
The mass number of an element is equal to the sum of the elements neutrons and protons.
neutrons + protons = mass number
The sum of protons and neutrons in an atom is called mass number.
Atoms which have different number of protons and neutrons but have the same molecular weight are called Isobars.
Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons.

Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
Atoms with more protons than neutrons are simply isotopes of an element. Atoms of an element always have the same number of protons. However, the number of neutrons can vary and can be higher, lower, or equal to the number of protons.
The mass number of an element is equal to the sum of the elements neutrons and protons.
neutrons + protons = mass number
The atomic number for an element with 54 protons is 54. For the atoms with 77 neutrons, the mass number would be 54 (protons) + 77 (neutrons) = 131. For the atoms with 79 neutrons, the mass number would be 54 (protons) + 79 (neutrons) = 133.
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. An example is carbon-12 and carbon-14, which both have six protons but differ in the number of neutrons they possess.
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
Atoms having the same number of protons and neutrons make up the same element.
