The energy required to remove two valency electrons of a metallic atom is called? a. second ionization energy b. ionization energy. c. electron affinity. d. activation energy

Option (a) is the correct answer.

Explanation:

Amount of energy needed to remove an electron from a neutral or gaseous atom is known as ionization energy.

The energy required to remove one valence electron from a neutral or gaseous atom is called first ionization energy whereas when two valence electrons are removed then it is called second ionization energy.

Thus, we can conclude that the energy required to remove two valency electrons of a metallic atom is called second ionization energy.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
