Are simple cations always larger or smaller than the neutral atoms from which they were formed?

They have very similar sizes. An ion is an atom that is missing one or more electrons. The contribution of individual electrons to the size of an atom is very slight.

∙ 12y agoCations have lost electrons to have the same electron gas configuration as a noble gas, so its highest energy level has the right number of electrons. Each row of elements on the periodic table represents an energy level, so the first row has 1 energy level, the second row has energy levels 1 and 2, and so on.

∙ 11y agoi think you are confused mate
ions are about gaining or losing electrons. they are described as charged particles
metals lose electrons hence they lose electrons of an orbit, while non metals gain electrons thus getting a full outer shell.
hence the ions of metal will have less electrons while that of a non metal will have more..

How does the size change when an atom forms a cation and when an atom forms an anion?
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.
Why cationic molecular ions are greater then anionic one?
It is wrong. Cations are smaller than ions. It is because when cations are formed the outer shell of the element is removed but this does not happen with anions.
What is the Definition and formation of cations and anions?
An ion is an atom which is not neutral i.e. it has excess of charge on it. There are two types of ions:Cation:- These have positive charge on them. They are formed when an loses electrons and protons exceed their number.Anion:- These have negative charge in them. They are formed when an atom gains electrons and no. of electrons exceed the no. of protons.
Which best explains why cations are smaller than atoms from which they are formed?
A cation has had electrons removed. So, although cations and their parent atoms have the same number of protons in the nucleus they have a different number (lower) of electrons. This means the same number of protons pulls the smaller number of electrons closer to the nucleus and so the remaining electrons are more tightly bound by the nucleus and hence the reduction in size.
What are ions and ionic bonds?
Ions are formed when atoms gain or lose electrons. Positively charged cations are formed when atoms lose electrons. Negatively charged anions are formed when atoms gain electrons. Ionic bond is the force of attraction between cations and anions.
Cations are formed by?
cations are positively charged ions formed by loss of electrons from the neutral atoms having 1,2,3 electrons in the outermost orbit
How are cations produced?
Cations are positively charged species and are formed when elements lose electrons.
Cations are formed when neutral atoms lose?
Yes, they loose electrons : e-
What are smaller cations or anions?
cations are smaller than the atoms from which they were formed because they lost an electron thus becoming smaller in size. anions are bigger than the atoms from which they were formed because they gained an electron and increasing in size. the greater the nuclear charge, the smaller they are.

How is a cat-ion formed?
cations are positively charged ions formed by loss of electrons from the neutral atoms having 1,2,3 valence electrons
How does the size of a cation compare with the size of the neutral atom from which it is formed?
An ion is an atom that carries a charge because it has more or less electrons than its neutral form. An electron weighs less than 0.06% of a proton and doesn't take up any real space, therefore an ion is not different in size than its neutral atom.
How does the size change when an atom forms a cation and when an atom forms an anion?
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.
What happened when you change a neutral atom into a positive charged atom?
Positively charged cations are formed when atoms lose the valence electrons.
How do the sizes of cations and anions relate to the atoms they form from?
Cations are formed when atoms lose electrons and hence are smaller in size than the corresponding atoms. Anions are formed when atoms gain electrons and hence are larger in size than the corresponding atoms.
What are metal cations?
Cations are ions with a positive charge. Metal cations are formed when metal loses electrons.
How does a cation achieve its charge?
Ions are charged atoms. When an ion loses one or more of its electrons it becomes a cation. Cations are positively charged ions. Cations can be formed from a metal by oxidation, from a neutral base by protonation, or from a polar compound by ionization.
Which of the following are always larger than the neutral atoms from which they are formed.. A. positive ions B. negative ions C. cations D. none of the above?
B. Negative ions. ( anions ) They have taken electron(s) into their valance shell and have increased their size this way.
