Yes, in general, molecules in cool substances are closer together than in hot substances. As substances cool down, their molecules lose energy and move more slowly, causing them to come closer together and form a more compact arrangement. Conversely, in hot substances, molecules have more energy and move rapidly, leading to increased distance between them.
Lithium can gain and lose electrons because it has three electrons in its outermost energy level. It can lose one electron to achieve a stable configuration like a noble gas, or gain seven electrons to complete its outer shell. This ability allows lithium to form different ions with different charges.
A substance gains thermal energy when it evaporates, as energy is required to break the intermolecular forces holding the molecules together and allow them to escape into the gaseous phase.
During evaporation, a substance gains energy from its surroundings to break the intermolecular bonds and escape as a gas. This results in a cooling effect on the surroundings as energy is absorbed by the substance.
Elements want to gain or lose electrons in order to achieve a stable electron configuration, usually by attaining a full valence shell of electrons. This helps them achieve a more stable, lower energy state, similar to the configuration of noble gases.
Most substances lose or gain energy when their temperature changes.
Lose
It can lose or gain energy or it forms the attractions between particles.
It can lose or gain energy or it forms the attractions between particles.
Several different outcomes can occur to reacting substances in chemical reactions. An atom will typically either lose or gain electrons, which will make it negatively or positively charged.
Energy does not have mass. It can be converted into mass (such as in nuclear reactions) or from mass (as in matter-antimatter annihilation), but the energy itself does not gain or lose mass.
When condensation occurs, it is a gain thermal energy.

C. Most substances will contract. When the temperature of a substance decreases significantly, its particles lose kinetic energy, causing them to move closer together. This results in a decrease in volume, known as contraction.
Metamorphic rocks gain enegry as they are melted by magma and then lose energy as they cool into igneous rocks.
Substances can change states through processes such as melting, freezing, evaporation, condensation, or sublimation. These changes occur when the temperature or pressure of the substance is altered, causing the particles to either gain or lose energy and rearrange themselves into a different state.
