An atom of nitrogen has seven protons in its nucleus. How many electrons does it have?
Assuming that the atom has no charge, the atom will have seven electrons. If the atom is positive, you subtract the charge from the atomic number to find the number of electrons. If the atom is negative, you add the charge to the atomic number to find the number of electrons.
What do electrons do in an atom?
They affect the charge of the atom.
When an atom has one or more extra electrons it will have a positive charge?
No. Electrons possess a negative charge, therefore an atom with an excess of electrons will have an overall negative charge.
What describes the charge of an atom before any electrons are transferred?
Neutral charge describes the charge of an atom before any electrons are transferred.
What has a negative charge and can move from atom to atom?
electrons

Is an atom of nitrogen with 7 protons 8 neutrons and 8 electrons an ion?
Yes. An uncharged atom has the same number of protons (+ve charge) and electrons (-ve charge). An atom with 7 protons and 8 electrons has an overall charge of [+7+(-8)=-1] so is an ion, it is called an 'anion' because it is negative. Positive ions are 'cations'.
How many electrons in a nitrogen ion?
The atomic number of nitrogen is 7. That means that nitrogen has 7 protons per atom, each one having a +1 charge. Assuming that the atom of nitrogen is electrically neutral, there must also be 7 electrons, each of them having a -1 charge, in order for the total charge of the atom to be 0.
If an atom has 5 protons and 7 electrons what is the charge of the atom?
its charge is 0. Protons have a positive charge, while electrons have a negative charge (neutrons have no charge at all). So ten protons will balance out ten electrons, making the net charge 0.
What do electrons do in an atom?
They affect the charge of the atom.
When an atom has one or more extra electrons it will have a positive charge?
No. Electrons possess a negative charge, therefore an atom with an excess of electrons will have an overall negative charge.
Is an atom that loses electrons have a negative charge?
No. Electrons have a negative charge and so removing one from the atom will give it a positive charge.
Is 7 protons and 7 neutrons and 9 electrons is an ion?
If the 7 protons and 7 neutrons are in the nucleus of an atom, and the 9 electrons are in the electron cloud surrounding the nucleus, then yes, this would represent an ion with a 2- charge. And, in looking at the periodic table, this would be a nitrogen atom with a 2- charge, which is hypothetical, since nitrogen atoms gain 3 electrons when forming ions, and would therefore actually have 10 electrons, and a charge of 3- . However, the important thing is that if an atom has an unequal number of protons and electrons, it is an ion.
Which part of an atom carries a negative charge?
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.
What describes the charge of an atom before any electrons are transferred?
Neutral charge describes the charge of an atom before any electrons are transferred.
What is the same between neutrons and electrons?
When the number of electrons and neutrons are the same, it means that the number of protons will also be the same amount. For example a nitrogen atom has 7 electrons and 7 neutrons, this means that the number of protons will also be 7.
When there is an equal number of electrons and protons in an atom what is the charge?
The atom is neutral. There is no charge.
