3
Twelve. Each proton has one positive charge.
2
A helium atom has two positive charges, as it contains two protons in its nucleus. These protons contribute to the atomic number of helium, which is 2. Additionally, helium typically has two electrons, which balance the positive charges, making the atom electrically neutral.
If an atom has 3 positive charges (protons) and 4 negative charges (electrons), the 3 positive charges would "cancel out" 3 negative charges, with one negative charge left over. So the atom would have a charge of -1.
Yes, in an atom, the negative charges of the electrons are balanced by the positive charges of the protons in the nucleus. This overall balance of positive and negative charges is what keeps the atom stable.
the positive number of a atom
The atom gets negative charges and positive charges from other things.
The charges of an atom are, protons are positive (+). Neutrons has a neutral charge or no charge(0) and electrons have a negative charge (-).
Electrons contain negative charges, and protons contain positive charges.
Thomson thought that the atom must contain positive charges because his discovery of electrons inside the atom indicated the presence of negatively charged particles. To balance the negative charge of electrons, there must be positive charges present within the atom.
protons
Protons. A balanced or stable atom has the same number of protons (positive charges) as electrons (negative charges), ensuring overall neutrality. If this balance is disrupted, the atom may become an ion, carrying a positive or negative charge.
