Question

dawkins, nasia cms physical science midterm summative assessment 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:

Step1: Analyze the charge change

A neutral atom \(K\) becomes \(K^{+}\).

Step2: Relate charge to electron transfer

In an atom, protons are in the nucleus and their number defines the element. Electrons are outside. A positive charge on an ion (\(K^{+}\)) means there is one more proton than electrons. Since the element \(K\) (potassium) remains the same (proton number unchanged), it must have lost an electron. Losing an electron gives a net positive charge.

Answer:

loss of an electron
