Chemistry deal with atoms and compounds made of atoms and while electrons are involved in chemical reactions, they are subatomic and therefore inside every atom and thus do not have a chemical formula.
There is no chemical formula for electrons. However, an extra negative charge is often written as a superscript minus.
The chemical formula for Beryllium is Be. A Be atom needs to lose 2 electrons to become stable, so it would have a charge of 2+
Electricity is not a chemical and it does not have a chemical formula. Electric current consists of moving electrons; static electricity consists of unmoving electrons.
The Chemical Formula for Calcium Citrate is Ca3(C6H5O7)2.
PO43-.This in superscript form, hence, the formula is one phosphorous, 4 oxygens, and 3- valence electrons.
8 means the number of electrons on the second valence layer.
When forming a compound the chemical formula or compound is made stable with a net charge of zero by the sharing of electrons (covalent compounds/molecules) or the transfer of electrons (ionic compounds).
berrylium has two electrons to get rid of to make it an ion (stable) so the the formulla would be be2+ or be++
Zinc chloride has the chemical formula ZnCl2.The total number of protons is 64; the total number of electrons is also 64.The number of neutrons depends on the isotopes of Zn and Cl.
Energy has no chemical formula as it is not a chemical.
The chemical formula for magnesium oxide is MgO. Magnesium has valency +2 and oxygen has -2. So, magnesium donates two electrons and oxygen gains two electrons to form ionic bond.The chemical formula for strontium oxide is SrO. Strontium has valency +2 and oxygen has -2. So, strontium donates two electrons and oxygen gains two electrons to form ionic bond.
Sulfate consists of 1 S, and 4 O and so has a charge of 2-. You can see this directly from the periodic table by checking what group these atoms are in. Sulfur and Oxygen are both in the 6th group, meaning they both have 6 valence electrons. So (6 electrons * 5 atoms) = 30 electrons. If we follow the octet rule (each atom must have 8 valence electrons for a full octet), then we need 2 more electrons. Sodium, Na, is in the 1st group on the periodic table, and therefore has 1 valence electron. So we need 2 sodium atoms, giving us the formula: Na2SO4 That is, 2 Na 1 S 4 O It's important to remember that when atoms 'share' their electrons by bonding, that BOTH atoms 'see' the electrons as theirs, meaning that, for example, although you may have 14 electrons between 2 atoms, as long as there is a single bond between the atoms they will both have full octets. For example: O2 :::O:O::: where : = pair of electrons.
Since Potassium is a element it does not have any chemical formula. It has a chemical symbol K, which is derived from its Latin name Kallium.
