What are the charges of the elements on the periodic table?
The usual charge of an element is common to its group.
- Group 1 (Alkali Metals): 1+
- Group 2 (Alkaline Earth Metals): 2+
- Groups 3-12 (Transition Metals): Variable positive charges.
- Lanthanide and Actinide Series: Variable positive charges.
- Group 13: 3+
- Group 14: 4+ or 4-
- Group 15: 3-
- Group 16: 2-
How do you find element charges?
To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.
What are charges chemistry?
In the context of chemistry and physics, charge usually refers to electric charge, which is a conserved property of certain subatomic particles that determines their electromagnetic interaction. Charge is a physical property that causes matter to experience a force within an electromagnetic field.
What group has elements with a +3 charge?
Group 3A
The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges.
What is the charge for all elements in group 17?
Elements in group 16 have a charge of -2, while all the elements of group 17 are halogens with a charge of -1 each.
What is the charge of PB?
+2 charge
Group IV A (14) metals form cations with +4 charge, although tin (Sn) and lead (Pb) can form cations having +2 charge. Generally, metals in this group are treated similarly to the “B” elements.
What is the charge of Fe?
2+
Table of Common Element Charges
| Number | Element | Charge |
|---|---|---|
| 26 | iron | 2+, 3+ |
| 27 | cobalt | 2+, 3+ |
| 28 | nickel | 2+ |
| 29 | copper | 1+, 2+ |
What does a +2 charge mean?
About this tutor › A neutral particle (no charge) has the same number of protons (+ charges) and electrons (- charges). If this particular particle now has a positive 2 charge (+2), that means it either gained 2 protons, or lost 2 electrons.
What does a 3+ charge mean?
The resulting cation has 11 protons and 10 electrons, and hence has a net charge of 1+. The net charge on an ion is represented by a superscript; +, 2+, and 3+ mean a net charge resulting from the loss of one, two, or three electrons, respectively.
Which elements have a charge?
Table of Common Element Charges
| Number | Element | Charge |
|---|---|---|
| 9 | fluorine | 1- |
| 10 | neon | 0 |
| 11 | sodium | 1+ |
| 12 | magnesium | 2+ |
What is the charge of group 7?
-1
Now, you can use periodic table trends to predict the most common element charges. Group I (alkali metals) carry a +1 charge, Group II (alkaline earths) carry a +2, Group VII (halogens) carry -1, and Group VIII (noble gases) carry a 0 charge. Metal ions may have other charges or oxidation states.

How do you know the charge of an element?
To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative. But you need to know the specific ionic charge elments.
Which is the most common charge of a chemical element?
Table of Common Element Charges Number Element Charge 32 germanium 4-, 2+, 4+ 33 arsenic 3-, 3+, 5+ 34 selenium 2-, 4+, 6+ 35 bromine 1-, 1+, 5+
What are the charges of the element hydrogen?
Table of Common Element Charges Number Element Charge 1 hydrogen 1+ 2 helium 0 3 lithium 1+ 4 beryllium 2+
How is the charge of an element related to its valence?
The charge on an atom is related to its valence electrons or oxidation state. An atom of an element is most stable when its outer electron shell is completely filled or half-filled. Although noble gas atoms almost always carry a charge of zero, these elements do form compounds, which means they can gain or lose electrons and carry a charge.
