-Fluorine
Chemistry
1 answer:
Mashutka [201]3 years ago
7 0
An ionic bond forms between an elemental metal and non-metal, characterized by the transfer of electrons from the metal to the non-metal in an attempt to mimic the stable octet.

A is the correct answer, as Potassium (a group 1 alkali metal) will donate an electron to Chlorine (a group 17 halogen). Potassium becomes more stable by removing the outermost shell, leaving behind a stable octet, and Chlorine completes its shell with the addition of the new electron. This trade of electrons forms their “ionic” forms, hence the reason for calling it an ionic bond. The other three form covalent bonds.

All of the cells in the body need oxygen. Hemoglobin molecules in red blood cells transport oxygen through the bloodstream. Oxyg
tankabanditka [31]

Answer:

High partial pressure of oxygen in the tissues.

Explanation:

Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.

When there is lack of oxygen in our bodies, we experience hypoxia.
