Which ion is larger? cu+ cu2+ why? because cu2+ has the filled 4s subshell. because cu2+ cannot be oxidized further. because cu2+ has a larger positive charge. because cu+ has one more subshell than cu2+. because cu+ has one more electron than cu2+.

ion size is larger than ion.

This is because has one more electron than .

Explanation:

Cations: They are formed when an atom looses its valence electrons. They are positive ions.

For positive ions, the removal of electron increases the nuclear charge for an outermost electron because the outermost electrons are more strongly attracted by the nucleus. So, the effective nuclear charge increases for cations and with that size of the ion also decreases.

As the positive charge on an ion increases the effective nuclear charges also increases which pulls remaining electrons present in the valence shell more closer towards the nucleus. Due to this size of an ion further decreases.

Also number of electrons in ions are more than that of the ions.

So, that is ion size is larger than ion.

h let me think

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
