Question

Write an equation that shows the formation of a copper (I) ion from a neutral copper atom

Answer 1

Answer: The equation is written below.

Explanation:

Copper is the 29th element of the periodic table having electronic configuration of $[Ar]3d^{10}4s^1$

When an atom looses an electron to form positive ion, it is called an oxidation reaction.

Copper will loose 1 electron to form +1 ion. The equation for the formation of copper (I) ion from neutral copper atom follows:

$Cu\rightarrow Cu^++1e^-$

Hence, the equation is written above.

Answer 2

Cu ----> Cu(+) + 1 e-
