Answer: increases by
As a chlorine atom becomes a negative ion, the atom "increases by" an electron
Explanation:
Chlorine atom has an atomic number of 17, and an electronic configuration of 1s2, 2s2 2p6, 3s2 3p5 showing 7 valence electrons in its outermost shell.
Hence, it receives a single electron to achieve a stable octet structure with electronic configuration of
1s2, 2s2 2p6, 3s2 3p6. Therefore, Cl- is a univalent negative ion with 8 valence electrons in its outermost shell. The increase is shown below
Cl + e- --> Cl-
Thus, as a chlorine atom becomes a negative ion, the atom "increases by" an electron
Burning of fossil fuels, increase use of vehicles and use of household appliances like refrigerator are the three ways humans have had an impact on the greenhouse effect on Earth
<u>
Explanation:</u>
-
Burning of fossil fuels for industrial purpose cause the emission of greenhouse gases such as Chlorofluorocarbons (CFCs), Carbon dioxide, methane and nitrous oxide.
- The smoke comes from the vehicles contain carbon dioxide which increases the number of greenhouse gases in the atmosphere
.
- Use of household appliances will also lead to the emission of greenhouses gases mainly, CFCs (Chlorofluorocarbons)
.
- Increase in the number of greenhouse gases in the atmosphere will lead to climate change.
