There are a great many things that gain and lose heat. Metals for example gain and lose heat much more quickly than gasses.
Water gains and loses heat much more quickly than land.
Isotope
lithium
An Ion. More specifically if it gains an electron it becomes an anion and it it loses an electron it becones an cation (pronounced Kat-ion)
Actually, a liquid becomes a solid when it loses heat, not when it gains heat. When heat is removed, the molecules slow down and eventually arrange themselves into a solid crystalline structure.
an ion is when an element loses or gains one or more electrons. an isotope is when a element loses or gains one or more neutrons. when one or more proton(s) is/are gained or lost, it becomes a different element.
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
When air loses its heat it actually becomes more dense and sinks which starts a convection current
No, water heats up slower than land because it has a higher specific heat capacity. This means that it takes more energy to raise the temperature of water compared to land or air. As a result, land heats up and cools down more quickly than bodies of water.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
When an atom combines chemically with another atom, it either gains, loses, or shares electrons to achieve a more stable configuration. This process results in the formation of chemical bonds, which can be ionic or covalent depending on how the electrons are shared or transferred between the atoms involved.
For an atom to form an ion, it has to either gain or lose one or more electrons. Usually this happens during a chemical reaction, when an element gains or loses electrons to achieve noble gas configuration.
