They are smaller and this is why:
There are less electrons to be attracted by the same original positive charge of the nucleus.
(For negative ions it's just the other way around.)
ATOMS are real life examples of atoms. They do exist.

A particle smaller than atom is a subatomic particle, protons , neutrons, and , electrons, the smallest one is an electron, smaller than that are point particles and elementary particles, one elementary particle and point particle is a quark, up quarks down quarks the smallest single thing found so far is a GLUON, which is the force which binds/holds quarks together. Where the devil lives in anti matter there are also atoms and subatomic particles and point particles but just anti, anti- GLUON, anti-QUARK, anti-ATOM, anti-SUBATOMIC PARTICLE. There is something called the string theory, and super string theory that theorizes about bosonic/boson strings but it can not be provine yet, and I think a gluon is still alot smaller than a bosonic/boson string if they are true. HOPE THIS HELPS
Cations are smaller then neutral atoms and anions are larger.
Metal ions are smaller than the neutral atoms they came 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.
An alloy made up of different sizes. Smaller cations can fit into spaces between the larger atoms
Atom 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.
Yes, considerably so. In general, positive ions are smaller than their neutral atoms, and negative ions are larger than their neutral atoms.
If you look at the structure of an atom you will see that the positive charges (protons), are secured in the centre (nucleus) of the atom along with the neutral charges (neutrons), while the negative charges (electrons) are situated in shells around the nucleus, and are therefore easier to get at.
Bromide ions are larger than bromine atoms because the ion has one more electron than the neutral atom. The extra electron is less tightly bound than the other electrons because it experiences a smaller effective nuclear charge. Other anions are also larger than their corresponding atoms for the same reason; cations, on the other hand, are smaller than their corresponding atoms because they have fewer electrons.
cations are positively charged ions formed by loss of electrons from the neutral atoms having 1,2,3 electrons in the outermost orbit
false
Yes, the size of a cation is smaller than it's neutral atom. This is so because cations have a low number of shells and hence a high effective nuclear charge which causes them to be smaller in size then their neutral atoms.
Cations are neutral atoms that have lost an electron or electron(s). They are positively charged. They are generally metals.
