Question

what change has taken place in the following?
k→k+
loss of a proton
gain of a proton
loss of an electron
gain of an electron

Explanation:

In an atom, protons are in the nucleus and determine the element's identity (for K, the number of protons is fixed as it's potassium). When \(K\) becomes \(K^{+}\), the charge changes from neutral (\(0\)) to \(+ 1\). Electrons are negatively - charged. Losing a negatively - charged particle (electron) will result in a positive charge. The reaction \(K
ightarrow K^{+}+e^{-}\) (where \(e^{-}\) represents an electron) shows that an electron is lost.

Answer:

loss of an electron
