This is why, at room temperature, iodine, which has the largest molecule, is a solid, bromine, which is the next in line in terms of size, is a liquid, and fluorine and chlorine, the smallest of the molecules, are both gases. So remember, nonpolar molecules only exhibit weak London dispersion forces.
For most women, the length of time between ovulation (when an egg is released from the ovary) and their monthly period is between 12 to 16 days (this is called the luteal phase). The first day of your menstrual cycle is the first day of your period (day 1). The period usually then lasts anything from 3 to 7 days. Youâll probably find that if you get any period pains, theyâll be at their worst in the first few days of your period.
Ovulation can occur at different times of a womanâs menstrual cycle, depending on the number of days of the womanâs cycle. The average menstrual cycle. is usually between 28 to 32 days. Women with a 28-day menstrual cycle usually ovulate between days 13 to 15, or about two weeks after the start of her period.
