The element that would lose an electron most easily among Mg, Na, K, and Ca is Potassium (K).

This is because of three main reasons:

1. Atomic Size: Potassium is the largest atom among these four. Larger atoms have their valence electrons further away from the nucleus, making them less attracted to the center. Therefore, they can lose an electron more easily.

2. Electron Configuration: Potassium has only one electron in its outermost shell (it's in the s1 state). This single electron is relatively easy to remove.

3. Ionization Energy: Potassium has the lowest first ionization energy among these elements, which means it requires the least amount of energy to remove the outermost electron.

So, based on these factors, Potassium (K) would lose an electron more easily than Mg, Na, and Ca.
