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.
The length of the cycle is measured from Day 1 of one cycle (bleed) to Day 1 of the next cycle (bleed). Your menstrual cycle length and the day of ovulation are directly related. Your menstrual period begins about 14 days after you ovulate. If ovulation occurs on approximately day 14 of a womanâs cycle then your next period starts about 14 days later and the cycle length is 28 days. Ovulation happens when a mature egg is released from the ovary. It is then picked up by the fallopian tube and is available to be fertilized.
