Which two particles are present in the nucleus of an atom? electrons and neutrons electrons and molecules protons and neutrons protons and electrons

Protons and neutrons

Explanation:

In a classic model (like a Bohr model) an atom is composed by 3 particles:

Electrons, which have a negative charge and orbit around the nucleus.

Protons, which have a positive charge and are located in the nucleus of the atom. Normally each element has a fixed number of protons.

Neutrons,which have a neutral charge and are found in the nucleus of the atom. An atom of the same element may have a different number of neutrons, and these are called isotopes.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
