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.)

What conclusions can we make about the size of cations neutral atoms and anions?

Cations are smaller then neutral atoms and anions are larger.


Are metals ions larger or smaller than neutral atoms they came from?

Metal ions are smaller than the neutral atoms they came from.


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.


Where do cations move?

Cations are positively charged ions that are attracted to the cathode (negative electrode) during electrolysis or in an electrical field. These ions move towards the cathode where they gain electrons to become neutral atoms.


What is the different and what is the same between an atom and an element?

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.


Why are positively charged atoms drawn smaller than negatively charged 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.


What type of atom do cations represent?

Cations are neutral atoms that have lost an electron or electron(s). They are positively charged. They are generally metals.


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. Metal atoms. - A


Why is a bromide ion larger than a bromine atom?

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.


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. Negative ions are formed when neutral atoms gain electrons, increasing their size due to the additional electron(s) while positive ions or cations are formed when neutral atoms lose electrons, reducing their size.


Cations are formed by?

Cations are formed by atoms losing electrons, resulting in a positively charged ion. This occurs when atoms from metals and certain nonmetals give up electrons to achieve a stable electron configuration. The loss of electrons creates a deficiency of negative charge, leading to a positive charge on the cation.


Cations are formed when neutral atoms lose?

Cations are formed when neutral atoms lose electrons, leading to a positive charge. This loss of electrons results in a higher number of protons compared to electrons in the atom, creating an overall positive charge.
