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¦.
A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1. The gain or loss of electrons by an atom to form negative or positive ions has an enormous impact on the chemical and physical properties of the atom.
