It would be antimatter, and a sample of it (as much of a waste as that would be) should annihiliate on contact with matter, releasing some amount of energy.
An atom is negative when there are more electrons which gives it that negative charge. An atom is positive when there are less electrons than protons.
An atom with more protons than electrons is a cation.
The neutrons do not affect the charge of an atom. The positive charge is on the proton the equal but negative charge is on the electron.If an atom has more electrons than protons it will have an overall negative charge.
The charge of an atom depends on the electrons compared to protons. Electrons being negatively charged, protons being positive. If there are more protons, the atom is positive, and if there are more electrons, the atom is negative.
If the atom has more electrons than protons than the atom will be negative.
A charged atom is called an ion.If it has more protons then electrons, it has a positive charge.If it has more electrons than protons, it has a negative charge.
The atom also has 15 electrons.
Protons are positive particles from the atomic nucleus; electrons are negative particles.
The electrons of an atom carry a negative charge. the electron cloud which is around the nucleus containing the electrons For more information, see Related links below.
The charge of an unionized atom is neutral, meaning it has an equal number of protons and electrons. Protons carry a positive charge, while electrons carry a negative charge that balances out the positive charge of the protons, resulting in a net charge of zero for the atom.
a) (well if it has different number of protons or electrons then it would be called an "ionized atom" either positive if more protons or negative if more electrons.) - if there are more neutrons inside the nucleus then protons you got isotopes - b) (well if it has different number of protons or electrons just look at the Periodic Table and count how many protons it has and look at the periodic table that will tell you what an atom will be )
No, only protons and neutrons exist in the nucleus of an atom. Electrons are what produce a negative charge.
