When they have lost 1 or more electrons, possibly in a atomic bonding situation, or due to collisions.
Protons have a positive charge in atoms.
An atom may be neutral, or it may have a positive or a negative charge. If it has a charge, it is called an ion.
Because protons have a positive charge and neutrons have no charge, the atomic nucleus has a positive charge.
No they do not.
Atoms with no overall charge are called neutral atoms. They have the same number of protons, which carry a positive charge, and electrons, which carry a negative charge. This balance of positive and negative charges leads to a neutral overall charge for the atom.
Positive atoms: cations. Negative atoms: anions
A polyatomic ion is a group of atoms with a charge.
The positive -charge in an atom is called the proton.They are held in the nucleus with the neutrons.
An atom with positive charge is cation.An atom with negative charge is anion.
In a water molecule, the hydrogen atoms have a partial positive charge. This is because the oxygen atom is more electronegative than hydrogen, pulling electron density towards itself and creating a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms.
a zewithalarion shows poth positive and negative; go figure...
Yes, the nuclei of atoms are electrically positive because they contain protons, which have a positive charge. The positive charge of the protons in the nucleus is balanced by the negative charge of the electrons orbiting around the nucleus.
