Answer:
It becomes negatively charged
Explanation:
An atom of chlorine having equal number of protons and electrons is neutral. The protons are the positively charged particles located in the nucleus of an atom. Electrons are negatively charged particles located outside the nucleus.
When the number of electrons and protons are the same, such an atom is neutral.
If the number of protons is more, the atom becomes positively charged.
In this case, the atom adds or gains an electron making the number of electrons to go from 17 to 18. This is more than the number of protons which are 17 by 1. The charge on the atom is therefore -1.
Answer:
A. it is the lowest at low temperatures
Explanation:
It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.
The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.
- Kinetic energy is directly proportional to the temperature of a substance.
- The higher the temperature, the more the kinetic energy of the molecules within a system.
- At low temperature, kinetic energy is the lowest.
- At the highest temperature, kinetic energy is the highest
