Negative
Boron has an atomic number of 5, which means that it has 5 protons in its nucleus. In a neutral atom, the number of protons is equal to the number of electrons surrounding the nucleus. Therefore, a boron atom has 5 electrons to balance the 5 protons.
An atom is considered neutral when the number of protons in its nucleus equals the number of electrons orbiting the nucleus, resulting in no overall charge. This balance of positive and negative charges makes the atom electrically neutral.
A nitrogen atom has 7 protons and 7 electrons as it is electrically neutral. (An atom always has same number of protons and electrons)
There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120
Protons are positive and the electrons are negative. Neutrons are neutral. Now we have the basis of the atomic particle charges. The atomic number is equal to the number of protons which is equal to the number of electrons. So if there are five positive particles and five negative ones, they balance each other out. With the acceptation of ions but that would take too long for me to type!
5*10^6 =5000000 5000000*(1.6*10^-19) = 3.125e25
It would have a negative charge, since the number of electrons - that have approximately the same amount of negative charge as the proton's positive charge in magnitude - is more than the number of protons. Neutrons have no charge (i.e. neutral).
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.

The number of electrons can be determined if the overall charge and number of protons are known. If the charge of an atom is neutral, then how ever many protons it has it will also have that number of electrons.
Protons are positive and the electrons are negative. Neutrons are neutral. Now we have the basis of the atomic particle charges.

An atom can become positive if it loses an electron. For example if the atom had five protons and five electrons, then loses an electron, it would have more protons making it more positive than negative.
Protons, neutrons, and electrons are the main particles of an atom. Protons are positively charged and are located in the nucleus of the atom. Neutrons are neutrally charged and are also located in the nucleus. Electrons are negatively charged and are located in the electron cloud, which is an area outside of the nucleus. Within an atom, there will typically be the same number of protons and electrons so the atom has a neutral charge (they cancel out). Neutrons are usually also the same number, although it is not uncommon for the neutrons to have their own population.
There are too many electrons. This would be a negative ion of lithium-6 (stable but less common isotope) that does not occur naturally. The element with 3 electrons, 3 protons, and *4 neutrons* is lithium-7, the most common isotope. It forms a stable positive ion (2 electrons).
