An atom contains an equal amount of positively charged particles (protons) and negatively charged particles (electrons). If a atom gains or loses electrons it then gains a charge and is no longer known as an atom; it becomes an ion.
Atoms have charges by the number of protons and electrons.
If there are more PROTONS than electrons, then the atom will be positive.
If the there are more ELECTRONS than protons, than the atom will be negative.
Neutrons are there in the atom too, but they don't have a charge and do not do anything to change the charge.
your cheating in mrs.wurt's aren't you? me too =P
By the equal numbers of protons and electrons.....
The number of protons is equal to the number of electrons. (the charge on a proton is equal in magnitude to the charge on a electron)
The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. Most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. visit page : denochearing .com/
The charge of an unionized atom is negative.
An atom may have a positive charge, a negative charge, or no charge. If it has a non-zero charge, it is said to be an ion.
When an atom has an electric charge it is called an ion.
In a electrically neutral atom, the number of positive charges in the atom's nucleus (with one charge being held on each proton in the nucleus), is balanced out by the number of negative charges present in the electron cloud round the nucleus (with one charge being held on each electron in the cloud). This means that in a neutral atom the number of Protons = the number of Electrons.
It would have 4 protons.
An atom does not have an overall electrical charge, because the positive charges in the nucleus are balanced by the negative charges in the electron cloud around the nucleus. When an atom loses or gains an electron, it is called an "ion".
Because Electrons have a negative charge (e-) and Protons have a positive charge (p+), so to create a balanced atom you must have the same number of e- as p+
A balanced atom is an atom that has it's outer energy level (AKA shell) completely filled in with 8 valence electrons.
Nickel has an atomic number of 28- so if there aare only 26 electrons - 2 are missing and the ion will have a harge of 2+.
This is a covalent bond.
Since an ion is a charged particle it would have to be when the protons and electrons are not balanced(a different number of protons and electrons) This would be the only way to get a positive or negative charge since neutrons have no charge anyway.
A proton has a charge of +1. Atoms are not charged because the positively charged protons are balanced by the negatively charged electrons.
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An uncharged atom of oxygen has 8 protons and 8 electrons. Sometimes it gains two electrons. This means that it has 8 protons but 10 electrons. +8 -10 = -2. therefore the charged atom of oxygen has a charge of -2.
it's convent

An atom with an equal number of electrons and protons has no net electrical charge, as the number of positive (proton) and negative (electron) charges are balanced.
