The number of protons, electrons, and neutrons in the atom of cr-24 is 28, 24, and 24 respectively.
<h3>What is atom?</h3>An atom is the smallest unit of matter, consisting of the positively charged nucleus and the electrons which move around it. The atom can not be divided further.
The atom of a matter is made by three elements-
- 1) Neutron-Neutron is the element of an atom, which has zero charge.
- 2) Proton-Proton is the element of an atom, which has a positive charge.
- 3) Electron-Electron is the element of an atom, which has a negative charge.
The atom of cr-24 has the atomic number 24. The atomic number of atom is equal to the number of proton and electron in an atom. Thus,
Now, if this atom has the mass number of 52 (most common). Then the number of neutron is,
Thus, the number of protons, electrons, and neutrons in the atom of cr-24 is 28, 24, and 24 respectively.
