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 answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
