No an electron does not have a net charge of 0, in fact it has a net charge of -1.
The charge on an electron is never equal to the charge on a neutron. An electron carries one negative charge and a neutron has no net charge.
There is zero net charge as the proton (+ve) and electron (-ve) cancel each other out and the neutron is neutral.
Protons and electrons share the property of electric charge. Protons are arbitrarily named "positive" charge, while electrons are negative. Their opposite but equal electrical charges cause them to attract each other, similar to gravity but about one billion billions (10^20) more powerfully.
It is a property, like mass. Not a particle. The electron and proton charges are considered to be the reference charges (-e and +e).
One electron.
The charge on an electron is never equal to the charge on a neutron. An electron carries one negative charge and a neutron has no net charge.
Every electron has a charge of minus one. If a neutral atom acquires an additional electron, then it also acquires the charge of that electron, and will have a net charge of minus one.
There is zero net charge as the proton (+ve) and electron (-ve) cancel each other out and the neutron is neutral.
If one electron is gained, then it has a charge of -1.
Yes. The magnitude of electrical charge on a proton is the same as the magnitude of electrical charge on an electron. The charge on a proton is positive and the charge on an electron is neutral, so that a pair containing one of each of them has no net electrical charge.
It depends on the charge on the atom at the start before it gains an electron. The electron has a charge of -1, and will make an atom more negative or less positive (both of which are the same thing). Let's look at the possibilities. If an atom is neutral (zero net charge) and gains an electron, it has a net charge of -1. If an atom is at +1 and gains an electron, it has a net charge of zero. If an atom has any positive charge, p, above +1, it has a net charge of p - 1. (A +5 would become a +4, and a +3 would become a +2.) If an atom has any negative charge, n, then its net charge becomes n - 1. (A -4 would become a -5, and a -2 would become a -3.)
since electrons are negative, you would subtract one from the original charge of the atom. For example, is the atom was neutral, the charge would then be 1-
If you assume that the iron is in equilibirum and there are initially as many protons as there are electrons, then the total charge is zero (because the protons and electrons cancel out). Now if you remove one electron (which has negative charge), you leave a net positive charge on the iron because there are more protons than there are electrons. In reality, I think electrons from other nearby iron atoms would fill the void because this "free sea of electrons" is a property of metals.
Protons and electrons share the property of electric charge. Protons are arbitrarily named "positive" charge, while electrons are negative. Their opposite but equal electrical charges cause them to attract each other, similar to gravity but about one billion billions (10^20) more powerfully.
One electron
It does not. In the atom, the protons carry a positive charge, and the electrons carry an equal negative charge. In a regular atom of this element, the charges are equal and thus there is no net charge. If an electron is lost, a positively charged ion is created.
one electron has a charge of 2.1×10−15 Z
