Actinium''s atomic syol is Ac with an atomic mass of 227 and an atomic nuer of 89. It is squishy and silvery-white. It glows blue in the dark because it is so radioactive that is excites the air around it.

Water fluoridation | Revolvy

Water fluoridation Fluoridation does not affect the appearance, taste or smell of drinking water.[1] Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride.[2]

Non-metals tend to gain electrons and form ions that have the same nuer of electrons as the nearest noble gases. For example, when a sodium atom gives up its single valence electron, it becomes a positively charged sodium ion. Its outer electron arrangement is like neons outer electron arrangement.
