Identify the missing information for each atom or ion. Note that the atoms and ions are not necessarily neutral.

A Se ion has a mass number of 78 and a charge of −2 . Determine the number of neutrons, protons, and electrons in this ion.
number of neutrons:
number of protons:
number of electrons:

Number of neutrons: 44

Number of protons: 34

Number of electrons: 36

Explanation:

The atomic number of Se (Selenium) is 34

Mass number is 78

Number of neutrons = mass number - atomic number = 78 - 34 = 44

Number of protons is the same as the atomic number

Number of protons = 34

Selenium ion has a charge of -2. This means it accepts two more electrons

Number of electrons = atomic number + 2 = 34 + 2 = 36

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
