An atom has 6 electrons, 6 protons, and 6 neutrons. you can tell that this atom belongs to the element because

The identity of the element always depends on the number of protons. In this case, since the atom has 6 protons, it must have an atomic number of 6. Therefore, this atom belongs to the element Carbon because it has an atomic number of 6.

The number of protons + neutrons (6 + 6 = 12) will indicate the atomic mass of the element. Meanwhile, the number of protons minus the number of electrons determines the charge of the atom (in this case, 6 - 6 = 0, so this is a neutrally charged atom).

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
