How does the size change when an atom forms a cation and when an atom forms an anion?
Wiki User
∙ 11y ago
A metal atom is smaller than the cation formed from it, because the electron(s) lost from a metal atom to form its cations are from the outermost electron shell or energy level of the atom. These electrons increase the size of the atom compared with the cation.

∙ 13y agoAtom is neutral while cation is positively charged so cations have less electrons than corresponding atoms, another difference is that cations are always smaller in size as compare to their respective atoms.

∙ 11y agoA cation has a smaller radius than the element from which it is formed, and the anion has a larger radius than the element from which it formed. Refer to the related links for a Periodic Table that shows atomic and ionic radii.

∙ 9y agoThe size of cation decreases as compared to its atom. this is due to removal of electron.

Is selenium cation or anion?
No. Selenium generally forms selenide (Se2-) ion
Which correctly describes cations and anions?
A. When an atom forms a cation, it becomes smaller than it does when it becomes an anion.
Is an atom of potassium most likely to become a cation or an anion?
A potassium atom will become a cation.
How does a cation differ from an anion?
A cation is a type of an ion, or a charged atom. An atom is the main module. They have the same number of protons and electrons. An ion has a different number between the two. A cation is just an atom with fewer electrons than protons.
What is an atom with an electrical charge on it called?
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
Is selenium cation or anion?
No. Selenium generally forms selenide (Se2-) ion
Which correctly describes cations and anions?
A. When an atom forms a cation, it becomes smaller than it does when it becomes an anion.
What forms when an atom has lost or gained electrons?
When an atom looses an electron is called "a cation, when gains is called an "anion".
What happens with the electrons when an atom froms a cation and an anion?
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
Is an atom of potassium most likely to become a cation or an anion?
A potassium atom will become a cation.
Is tin cation or anion?
Tin itself is a neutral element and therefore neither a cation nor an anion. A single tin atom can form a cation by donating two or four of its electrons to more electronegative atoms. A single tin atom is not electronegative enough to form an anion, but together with oxygen atoms, a tin atom can form a polyatomic anion.
Which atom becomes the anion in calcium chloride?
In CaCl2, Cl- is the anion while Ca2+ is the cation.
What is a charged atom?
A charged atom is an ion. A positively charged version is a cation and a negatively charged one, an anion.
How does a cation differ from an anion?
A cation is a type of an ion, or a charged atom. An atom is the main module. They have the same number of protons and electrons. An ion has a different number between the two. A cation is just an atom with fewer electrons than protons.
What is an atom called after an ionic bond?
Ions. And they can also be called anion or cation depending on their charges. An anion is a negative ion, a cation is a positive ion.
Is tin an anion or a cation?
Tin on its own is a neutral atom but will form cations since it is a metal.
What is an atom with or a negative charge called?
It's an ion. Cation for positive and anion for a negative atom
