Question

question 16 (5 points) fill in the symbol, mass, protons, neutrons, electrons for each of these using the periodic table you revied in class or from this link. assume all of these atoms are neutral. xenon blank 1: blank 2: blank 3: blank 4: blank 5:

Explanation:

Step1: Find symbol on periodic table

Xenon's symbol is Xe.

Step2: Determine atomic number

Xenon has an atomic number of 54, so the number of protons is 54.

Step3: For neutral atom

Since it's neutral, number of electrons = number of protons = 54.

Step4: Find mass number

The most common isotope of xenon has a mass number of 131.

Step5: Calculate neutrons

Number of neutrons = mass number - number of protons = 131 - 54 = 77.

Answer:

Blank 1: Xe
Blank 2: 131
Blank 3: 54
Blank 4: 77
Blank 5: 54
