What is an ion? a) an atom that has either gained or lost electron(s)b) an atom that is sharing electrons with another atomc) an atom that loses all of its protonsd) an atom that has lost one or more neutrons

a) an atom that has either gained or lost electron(s)

Explanation:

A neutral atom is an atom that has equal numbers of protons and electrons, its charge is neutral. These atoms are not stable (exceptions are the noble gases), so they need to gain, lose or share electrons to be stable.

When an atom gains or loses electrons, it became an ion, and its charge will not be more neutral. If it gains electrons (which are negative particles) it will have a negative charge and will be called anion; if it loses electrons, it will have a positive charge and will be called cation.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
