An ion is an atom or molecule where the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
So Fe2+ is an ion because it has a charge of 2+, whereas He does not have a charge. In this example, Fe has lost 2 electrons giving it an overall charge of 2+ since it has more protons than electrons for the neutral state. Therefore, it is an ion, (particularly a cation because it has positive charge. Negative charge is called an anion). He, however, has an equal number of protons and electrons, resulting in no net charge. Therefore it is not an ion.

What is the common ion charge for the element Li?
The common ion charge for the element Lithium (Li) is +1.
What can be concluded if an ion of an element is smaller than an atom of the same element?
If an ion of an element is smaller than an atom of the same element, it suggests that the ion has lost electrons compared to the neutral atom. When electrons are lost, the outer electron shell contracts, making the ion smaller. This typically occurs when an element forms a positive ion by losing one or more electrons.
If an element is missing one electron... is it a positive ion negative ion different element or different isotope?
If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
Period 3 element that forms a 3- ion?
The third period element that forms a 3- ion is sulfur.
Is fluoride ion an element?
Fluoride ion (F-) is not an element, but an ion formed from the element fluorine (F). Fluorine is a chemical element on the periodic table, while fluoride ion is a negatively charged particle resulting from the gain of an electron by a fluorine atom.

An ion is an element that has a what charge?
An ion is an atom of any element that either has a positive or negative charge.
What does an element's atomic number tell about that emelent?
The number of protons in each nucleus of an atom of the element. Also if this element is an atom and not an ion (has no charge) the Atomic number is equal to the number of electrons in its quantum shells
Is iodide an element?

What is the common ion charge for the element Li?
The common ion charge for the element Lithium (Li) is +1.
Is C6H12O6 an ion or an element?
C6H12O6 is a molecule, specifically glucose. It is not an ion or a single element, as it is composed of carbon, hydrogen, and oxygen atoms bonded together.
What can be concluded if an ion of an element is smaller than an atom of the same element?
If an ion of an element is smaller than an atom of the same element, it suggests that the ion has lost electrons compared to the neutral atom. When electrons are lost, the outer electron shell contracts, making the ion smaller. This typically occurs when an element forms a positive ion by losing one or more electrons.
Which element forms an ion with the same charge as the ammonium ion?
The element hydrogen forms an ion with the same charge as the ammonium ion, which is +1. When hydrogen loses an electron, it becomes a hydrogen ion with a +1 charge, just like the ammonium ion.
