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.
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
What atom has the larger atomic radius F or Fr?
Fr
When does the radius of an atom decreases or increases?
the radius of an atom gets larger when moving left to right across the periodic table because elements gain protons and electrons- the increase in charge brings the atom radius in
Is a gold atom or a hydrogen atom larger?
Atomic (covalent) radius of hydrogen is 31 pm. Atomic (covalent) radius of gold is 136 pm.
What is going to happen to the size of a positive ion as compared to the original atom?
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
What is the relationship between the radius of a anion and that of the atom from which it is formed?
Anions are much larger than their corresponding parent.
What occurs to the radius when an atom loses an electron?
The negative ionic radius is larger than the neutral atomic radius
When an atom loses one or more electrons does the radius of the atom become smaller or larger than the radius of the atom?
please be more specific and I might be able to answer this correctly
Which element will have a larger atomic radius magnesium or cesium?
Caesium atom has a larger atomic radius.
Which changes occurs when a barium atom loses two electrons?
It becomes a positive ion and its radius decrease
When an atom of chlorine forms an ionic bond with an atom of sodium does the atom of chlorine become an ion with a smaller or larger radius than the atom of chlorine?
It becomes an ion with a larger radius than the atom of chlorine
Which atom has the larger atomic radius K or Li?
K (potassium) has the larger atomic radius.
Does lithium form a negative or a positive ion?
This has a positive ion as it only has 1 electron on its outer shell, so rather than gaining 7 for a full shell of 8, it loses 1 to have a full outer shell.The radius of the Li+ ion can be estimated by subtracting the radius of the I- ion .In each case, the negative ion is much larger than the atom from which it was formed.
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
a larger nuclear charge
