Argon

Explanation:

This is because argon is in group 8 of the periodic table. Group 8 metals have a full outer shell, so they don't need to react with another element to get those/ lose those electrons.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
