What is symbol and charge?
When writing the symbol for an ion, the one- or two-letter element symbol is written first, followed by a superscript. The superscript has the number of charges on the ion followed by a + (for positive ions or cations) or – (for negative ions or anions). Neutral atoms have a charge of zero, so no superscript is given.
Which ion is always written first?
cation
Rule 1. The cation is written first in the name; the anion is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.
What will be the charge on aluminum when it fulfills the octet rule?
+3 because all Group 13 ions will lose 3 electrons (this is easier than gaining 5 electrons!) to fulfill the Octet Rule. For example Aluminum’s ion possesses 13 protons and 10 electrons- it’s overall charge is +3.
Is sulfur positive or negative?
Sulfur is in group 6 of the periodic table. What is the charge on its ions, and is the charge positive or negative? The charge is negative, since sulfur is a non-metal. The charge on the ion is (8 – 6) = 2.
What is the symbol and charge for beryllium?

| A | B |
|---|---|
| beryllium ion | Be2+ |
| magnesium ion | Mg2+ |
| calcium ion | Ca2+ |
| strongtium ion | Sr2+ |
What does it mean if an element has a charge?
The atomic number of an element, also called a proton number, tells you the number of protons or positive particles in an atom. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge.
Does the positive or negative ion come first?
Ions form when atoms gain or lose electrons. Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged; an atom that gains one or more electrons becomes negatively charged.
How to find the molecular formula for dichromate?

What’s the difference between dichromate and chromate?
Chromate (Cr2O7 2-) Dichromate (Cr2O72-)
How is dichromate a divalent inorganic anion?
Dichromate(2-) is a divalent inorganic anion obtained by removal of both protons from dichromic acid. It is a chromium oxoanion and a divalent inorganic anion.
What is the color of ammonium dichromate when heated?
Ammonium dichromate is a bright orange red crystalline solid. It is readily ignited and burns producing a voluminous green residue. If heated in a closed container, the container may rupture due to the decomposition of the material. It may also act as a strong oxidizing agent if mixed with or contaminated with combustible material.
