Atoms are neutral all the time. Because there are equal number of electrons and protons in the atom it becomes an ion or charged if electrons are released or accepted by an atom. If the number of electrons are kept equal to the number of protons, the electrically neutral atoms can be made.

What is the charge on a neutral atom if it loses 3 electrons?
Depending on the atom, if it loses an electron it will become positively charged. In some cases it will also become unstable. All stable atoms are neutral, because there is always an equal amount of positively charged protons as there are negativity charged electrons. If the atom loses a positively charged proton, then the overall charge of the atom will become negative and vice versa.
What is the overall charge of an atom?
Are you in Mrs.barbaras class? In an atom the charge has to be 0, as protons and electrons balance each other out, or the atom can't exist. In ions, the charge is either positive or negative depending on the group the ion is in. E.G. Sodium (Na) has a charge of 1+ Chlorine (Cl) has a charge of 1-
What is the ionic charge of argon?
Argon doesn't have an ionic charge because it is a noble element which means that it neither gains nor loses electrons. Note- see octet rule :)
What is the formal charge on the hydrogen atom in HBr?
The formal charge on the hydrogen atom in HBr is 0
What is the formal charge for BrO2?
The formal charge on bromine in the molecule HBr is -1. There are a number of rules for assigning the formal charge to an atom. The most important of them is that the sum of the formal charges on each atom must equal the charge on the molecule or ion. Since the Br has a formal of -1 and the charge on HBr is zero, then the formal charge on the hydrogen atom must be +1. The bromine atom has a formal charge of -1 because another important rule is that the most electronegative atom will have a negative formal charge equal to the number of electrons it needs to fill all of its outer orbitals. Since bromine has seven electrons, it needs one electron to fill its outer shell.
What is the rule for neutral atom?
A neutral atom has an equal number of protons and electrons, which balances the positive and negative charges. This balance results in no overall electric charge for the atom. For example, a carbon atom has six protons and six electrons, making it neutral. The number of neutrons can vary, leading to different isotopes of the same element, but they do not affect the atom's charge.
How do you convert a neutral sulfur atom to an anion carrying a charge of -2?
You can convert a neutral sulfur atom to a sulfide anion (S2-) by adding two extra electrons to the sulfur atom. This will give sulfur a total of 18 electrons and a formal charge of -2, satisfying the octet rule.
What is the charge of an atom that has lost an electron?
This atom become a cation with a +2 electrical charge. All atoms have are neutral because the numbers of protons and electrons are equal. When you subtract any number n of electrons, the new charge is +n, just as a general rule.
What is the charge on a neutral atom if it loses 3 electrons?
Depending on the atom, if it loses an electron it will become positively charged. In some cases it will also become unstable. All stable atoms are neutral, because there is always an equal amount of positively charged protons as there are negativity charged electrons. If the atom loses a positively charged proton, then the overall charge of the atom will become negative and vice versa.
Atoms have what kinds of electric charge?
As a rule, atoms do not have a charge, that is why they are atoms.Different parts of the atom has a charge:proton - relative mass of 1 - charge of +1neutron - relative mass of 1 - charge of 0electron - relative mass of about 1/2000 - charge of -1A atom has a equal number of electons and a equal number of protons, and so no charge

How do you determine the charge of a molecule?
The charge of an ion is a result of the atom gaining or losing electrons. Determining this is the difference between the number of protons and the current number of electrons. For instance, an atom of potassium that has lost an electron would have a +1 charge.
Do the electrons of an atom contribute to mass of an atom?
Protons have a positive charge and weigh 1 AMU Neutrons have a neutral charge and weigh 1 AMU Electrons have a negative charge and 1184 electrons weigh 1AMU so they are thought to add nothing to the mass of an atom. You may want to check out Bohr's model or the duet/octet rule.
How many electrons surrounding an atom supposed to have?
An atom is supposed to have an equal number of electrons and protons, leading to a neutral charge. The number of electrons surrounding an atom is determined by its atomic number, which also dictates its place on the periodic table.
