Why do electron clouds repel?
Yes, electron clouds have a negative charge. The electrons make up electron clouds (naturally) and the electron carries a negative electrostatic charge. Since electrons carry a negative electrostatic charge, and, by a fundamental principle of electrostatics like charges repel each other, the electrons don't like each other. That's one of the guiding principles behind electron spin and the structure of electron orbitals in chemistry and biochemistry. The big fat positive charge on the nucleus captures the electrons, but the electrons have to decide amongst themselves how they're gonna get along out in the electron shells. And they do. Is it any wonder that electron shell structures rule most of chemistry?
How does the rule of zero charge help you predict the formula of an ion compound?
The rule of zero charge helps you predict the formula of an ionic compound because you know that what anion is present, the action that bonds will make the net charge zero.
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
Does electricity flow from the positive to the negative terminal or the negative to the positive terminal?
That's a convention. It could be drawn the other way, but it is better to stick to the convention, to avoid confusion.That's a convention.

How can you make salt dissolvable in oil?
Salt will dissolve in oil very slightly but not truly. salt is an ionic compound (it has a positive/negative side) and oil is usually covalent (there is no charge). The rule for solubility of compounds is that like dissolves like, so ionic dissolves ionic and covalent dissolves covalent.
What is a rule for making a negative ion which has a negative charge?
A negative ion is formed by the addition of negatively charged electrons. The protons do not change.
How is the ion of sulfur formed?
sulfur has 16 electrons with a neutral charge the most common ion formed is the sulfide ion, with a negative 2 charge to get a negative 2 charge, it gains 2 electrons, thus fulfilling the octet rule and acquiring the electron configuration of argon
What is the rule for adding a positive and negative number?
Adding a positive and negative number, the sum will always be negative. Example: 10+-20=-10 If you add two negatives, they cancel each other out making it positive.
What is the fundamental rule for electric charge?
Fundamental laws of electric charges: opposite charges (positive and negative) attract, similar charges (positive and positive or negative and negative) repel, somtimes charged objects will attract a neutral object.
Why does a negative times a negative equals a positive?
It is a rule in math!
Does PO4 negative three charge 3 obey the octet rule?
The oxygen atoms in the ion do obey the octet rule. The phosphorus atom has more than eight electrons in its valence shell. It is because of the existence of vacant 3d orbitals.
What is the rule for subtracting negative numbers?
The rule for subtracting negative numbers is 'when you are subtracting a negative number from a positive or negative, you must always add it.'Example: 3--3 = 3+3 = 6
What is the rule when multiplying a negative tims a negative?
The product is always positive.
What is the rule of determining formula of chemical compounds?
The sum of the positive charge must equal to the sum of negative charge Ex. sodium chloride sodium=Na+ chloride=Cl- Formula=NaCl
Which is positively charged non metallic ion?
The rule of thumb for determining the charge of non-metal ions is that if it is in groups 1 through 3 or transitional it has a positive charge, if it is in groups 5 through 7 it will have a negative charge.
Why is that negative number multiplied by a positive number a negative number?
Because that is the rule. negative * negative=positve positive *negative=negative and vice versa
What happens to electrons when they go near a negative charges?
They get repelled away from the negative charge(-) because electrons have anegative charge(-).The rule is that same polarities, in this case (-) and (-), repel each other and opposite polarities, (+) and (+), attract each other. (+) and (-) atom bonding is called Ionic bonding because the atoms have to be ions, either cations(+), or anions; to electromagneticallybond.
