What does is mean to say a charge is quantized?
It means the charge is an integer multiple of some basic charge. If the charge consists of a certain number electrons, you can have 1 electron, 2 electrons, 3 electrons, etc., but you can't have 1.5 electrons, or pi electrons.
Which electrons have the most energy in an atom?
All electrons in an atom have: * a negative one charge * 1/2 spin * 0.511 MeV of mass
A particle has 4 protons and 3 electrons what is the net charge?
2
When does the charge exist?
When a material has an excess of electrons, it has a negative charge. When it has a deficiency of electrons, it has a positive charge.
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.
Why does a element have a plus 2 charge?
An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
If you have 3 neutrons and 2 electrons what charge do you have?
-2 neutrons = 0 = no charge electrons = -1 = negative charge positrons = +1 = positive charge
What particle has a -3 charge and 36 electrons?
a bromine ion will have 36 electrons and a -1 charge
What is the charge of magnesium with 2 less electrons?
negative charge
What is the charge on a magnesium ion that has ten electrons?
The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
What is the total charge if you have 14 protons 14 neutrons and 12 electrons?
If the atom is stable and neutral, it will have 14 electrons. If it has a positive charge it will have less electrons, and if it has a negative charge it will have more electrons.

When does an atom become an ion with a charge of 2 plus?
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
How can you find the charge of atom by the electrons?
Electrons have a -1 charge while protons have a +1 charge. Thus, subtracting the number of electrons from the number of protons gives the charge of a species. For example, if a lithium ion has 3 protons and 2 electrons, it has a +1 charge.
If 2 electrons where added to oxygen atom what would be the charge?
All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions. Gaining electrons- If atoms gain electrons then they are getting negatively charged particles making them have a negative charge. Losing electrons- If atoms lose electrons then they are losing a negative charge and they become a positively charged ion. Oxygen- Oxygen will have a negative charge before a positive charge because it needs only two electrons to have a stable valence level. For example, Oxygen will take the electrons from two Hydrogen atoms and make H20.
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
How many electrons does the element selenium have with the charge of negative 2?
It should gain 2 electrons
