One degree is 1/360 of the way around a circle and therefore 1/360 of the moon's orbit around the earth. 1/360 of one month is on the order of a couple hours.] This page was last updated June 28, 2015. The Earth.
DNA is negatively charged because of the phosphate group that is in each nucleotide. DNA also has a negative charge because of the phosphate icons in its chemical backbone.â¦.
Mg has 12 protons in its nucleus - these are positively charged Surrounding the nucleus are 12 negatively charged electrons. Because the number of positive charges matches the negative charges, the atom is overall neutral The neutral atom can lose 2 electrons from its outer shell. This leaves 12 positively charged protons, and only 10 negative charged electrons The magnesium ion has 10 electrons and a charge of 2+ . The Mg atom - like all atoms - does not lose protons from the nucleus, in the chemistry that you are studying. It can only lose or gain electrons.
