Question

explain which of these ions is larger, and why: cu⁺ or cu²⁺. part: 0 / 2 part 1 of 2 which ion is larger? cu⁺ cu²⁺ part: 1 / 2 part 2 of 2 why? because cu⁺ has one more electron than cu²⁺. because cu²⁺ cannot be oxidized further. because cu⁺ has one more subshell than cu²⁺. because cu²⁺ has the filled 4s subshell. because cu²⁺ has a larger positive charge.

Explanation:

For the first part, ionic size is related to the number of electrons. $Cu^{+}$ has one more electron than $Cu^{2 +}$, resulting in greater electron - electron repulsion and a larger size. For the second part, the reason $Cu^{+}$ is larger is that it has one more electron, which increases the electron cloud size.

Answer:

Part 1 of 2: Cu⁺
Part 2 of 2: Because Cu⁺ has one more electron than Cu²⁺.
