Potassium (atomic number 19) has a single electron in its outermost shell. What type of bond is potassium most likely to be involved in?

Ionic bonding

Explanation:

Well firstly it cant form a covalent bond because its a metal. So that leaves ionic and metallic bonding.

Its more likely to form an ionic bond because it has one electron which it needs to get rid of to complete the shell and an element that would need the extra shell would be a group 7 element like neon which only has 7 electrons on its outermost shell. The potassium and neon would react so that the neon could take the electron from the potassium to complete the shell and in turn that would also leave potassium with a full shell making them both stable.

I hope this kinda helped

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
