If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
This energy is released as a photon.
What happens when molecules lose energy?
They get colder.
How can energy be conserved if a substance must gain or lose thermal energy to change state?
Heat is a form of energy. It is just being transferred to the temperature bath (air, water, whatever). It hasn't been destroyed.
Why is HC2O4- amphiprotic in water?
Because it is able to react with both acids and bases to form substances. In other words, it can either gain or lose a hydrogen proton/ ion. Hope this helps.
What cannot change in an atom is it protons neutrons or electrons?
An atoms protons cannot change.The number of neutrons can change (gain or lose) to form an isotope (ex. Hydrogen naturally has no neutrons. But it can gain neutrons to form Heavy Hydrogen, or in other words, a Hydrogen Isotope).An atom can gain or lose electrons to form an ion. Usually an atom will gain or lose electrons to fill its valence (outermost) shell. It takes just as much energy to gain an electron as it is to lose one, so an atom will always look to lose or gain the least amount of electrons possible. (ex. Oxygen has 6 valence electrons. It will look to gain 2 electrons, rather than lose 6).Protons: DO NOT CHANGENeutrons: Can change to form an isotopeElectrons: Can change to form an ion
When do most substances lose or gain energy?
Most substances lose or gain energy when their temperature changes.
When compounds gain electrons they lose or gain energy?
Lose
What happens to the temperature of substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
What happens to temperature of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
Do particles lose or gain energy when changing from a liquid to a gas?
They lose energy.
What happens to the substances involved in a chemical change?
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.
What do magnetically soft substances do?
magnetically soft substances gain there magnetism easily but also lose it easily
Does gas lose or gain thermal energy in condensation?
When condensation occurs, it is a gain thermal energy.
How do objects gain or lose energy?
lose energy: gravity, otherwise see neuton's laws
Does a substance gain energy when it freezes?
Lose
Does steam gain or lose energy when it condenses to form water?
lose
What happens when oceans gain and lose heat slowly?
Nothing Happens
