Why 17cl- has a negative charge?

The negative sign implies that chlorine has gained an electron, which chlorine will easily do in a chemical reaction. The negative charge means the electrons now outnumber the protons 18-17, hence the negative 1 charge. (remember, electrons are negative.)


What are the charging of protons electrons and neutrons?

Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge.


What can be a negative for electrons or a positive for protons?

The charge of electrons is negative and of protons is positive.


What charges do proton an electrons have?

Pprotons have a positive charge neutrons have no charge and electrons have a negative charge. However the one with the smallest mass is electrons.


When a chlorine atom gains an electron what is it charge?

when the chlorine atom gains an electron its charge becomes -1. this is because the total number of electrons for chlorine is now 18. protons and electrons have the same atomic number, but when a chlorine ion forms it has one extra electron compared to the number of protons therefore giving it a negative charge of 1.


Whats the difference between electrons and protons?

Electrons have a negative charge and protons have a positive charge.


What do protons and electrons have that neutrons do not?

Protons and electrons both have a positive or negative charge, but neutrons have no charge.


What are protons neutrons and electrons hint charge?

Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge


What is the Definition of neutrons protons and electrons?

Neutrons: no electrical charge Protons: positive charge Electrons: negative charge


What are the thee particles of the atom respective charges are?

They are neutrons, protons and electrons. The neutrons have zero charge, protons have a positive charge and electrons have a negative charge.They are neutrons, protons and electrons. The neutrons have zero charge, protons have a positive charge and electrons have a negative charge.


What would happen to an object if number of protons and electrons are not equal?

You get charge discrepancies in the atom. So an atom that has more electrons than protons (say a chlorine anion) will have a net, negative charge. An atom that has more protons than electrons will have a net positive charge. A charged particle is more reactive than a neutral one.


The negative part of the atom?

The electrons. Protons are the positives and the neutrons are nothing. _______________________________________________________ The electrons carry negative charge. The protons carry positive charge. Neutrons have no charge.
