density=mass/volume plug and chug your numbers to find out
Chemistry
That is correct. Electrons have a negative charge to them. Atoms typically have an equal number of protons, which are positive, to electrons. This makes the atom neutral. By losing an electron, and taking away a negative force, you weigh the atom on the positive side making it...
