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:
C) The products have more energy stored in their chemical bonds.
Explanation:
In such reactions that absorb energy, the products have more energy stored in their chemical bonds.
For endothermic changes, heat is absorbed from the surrounding hence the surrounding becomes colder at the end of the changes.
The heat energy level of the products is higher than that of the reactants.
- Exothermic reactions releases heat to the surroundings. The sum of heat contents of the products is less than that of the hat contents of the reactants.
- Examples of such processes are burning and dissolution.
The ozone layer acts as an invisible shield and protects us from harmful ultraviolet (UV) radiation from the sun. In particular, the ozone layer protects us from the UV radiation, known as UV-B, which causes sunburn.
Ozone is a colorless, odorless reactive gas comprised of three oxygen atoms.
