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.
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 do electrons do in an atom?
They affect the charge of the atom.
An atom that has plus 1 charge must have fewer what than usual?
Electrons. Electrons carry a negative charge so when one is removed from the atom the atom gains a net positive charge.
When an atom in no longer neutral it exists with a charge an atom that has a charge is called a?
When an atom is no longer neutral and has gained or lost electrons, it is called an ion. An atom that has gained electrons will have a negative charge (an anion), while an atom that has lost electrons will have a positive charge (a cation).
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.
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.
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'.
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.
How many electrons in a nitrogen ion?
A nitrogen ion can have different charges, but for example, a nitrogen ion with a +3 charge would have lost 3 electrons from the neutral nitrogen atom (which has 7 electrons). Therefore, the nitrogen ion with a +3 charge would have 4 electrons.
What particles around the atom have negative charge?
only the electrons have a negative charge but they go around the nucleus
Which particles affect the charge of an atom or ion?
The particles that affect the charge of an atom or ion are electrons and protons. Electrons have a negative charge and protons have a positive charge. The number of electrons and protons in an atom or ion determines its overall charge.
Nitrogen atoms have 7 protons how many electrons are in an ion with a charge of plus 5?
A nitrogen atom has 7 protons and 7 electrons as it is electrically neutral. (An atom always has same number of protons and electrons)
What subatomic particles determine the charge of an atom?
Protons (+1 charge) and electrons (-1 charge) are the subatomic particles that determine the charge of an atom. Protons carry a positive charge, while electrons carry a negative charge. The number of protons in an atom determines its overall positive charge, while the number of electrons determines its overall negative charge.
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 do electrons do in an atom?
They affect the charge of the atom.
Charge of an atom?
The charge of an atom is determined by the balance of protons and electrons it contains. Protons carry a positive charge while electrons carry a negative charge. When an atom has an equal number of protons and electrons, it is electrically neutral. If an atom gains or loses electrons, it becomes an ion with a net positive or negative charge.
