Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent atom. =]
What is the name of a iodine ion?
The iodine anion is iodide. (I^(-)).
Is iodine a metal or non-metal and what ion does it form?
Iodine is a nonmetal and it forms the iodide ion, I-.
Is a negative ion larger or smaller than its parent atom?
Larger because a negative ion contains more electrons than its parent atom therefore it is larger. A positive ion would be smaller because it has less electrons than its parent atom.
Why is nitrogen ion larger than fluoride ion?
The nitride ion has a larger negative charge than the fluoride ion and a smaller positive charge in its nucleus, which means a greater repulsion within the electron shells and a lesser attraction to the nucleus.
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
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent atom. =]
A calcium atom is larger than a calcium ion because?
When it becomes an ion it is loosing electrons causing the effective nuclear charge to increase which draws the remaining electrons in closer which makes the ion smaller than the atom.
Is potassium ion larger then a potassium atom?
No, it is smaller
Why does the concentration of iodine ions remains constant in the iodine clock reaction?
Iodine ion is not consumed; in the first step the iodine ion is oxidized to iodine, in the second step iodine is reduced to iodine ion.
Which of these is most likely the correct symbol for an iodine ion?
The symbol for an iodine ion is I- .

Is a negative ion larger or smaller than its parent atom?
Larger because a negative ion contains more electrons than its parent atom therefore it is larger. A positive ion would be smaller because it has less electrons than its parent atom.
What noble gas has the same configuration as an iodide ion?
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
What is the formula for iodine ion?
I
