Answer

Explanation:

Step1: Find chlorine's atomic number

Look up chlorine (Cl) on periodic table. Its atomic number is 17.

Step2: Determine protons in Cl atom

The number of protons in an atom is equal to its atomic number. So, a Cl atom has 17 protons.

Step3: Find tungsten's atomic number

Look up tungsten (W) on periodic table. Its atomic number is 74.

Step4: Determine protons in Te atom

Look up tellurium (Te) on periodic table. Its atomic number is 52. So, a Te atom has 52 protons.

Step5: Answer neutron - related question

The periodic table does not give the exact number of neutrons in an atom. It gives the atomic number (number of protons) and the atomic mass (average of isotopes). Since isotopes of an element have different numbers of neutrons, we cannot determine the exact number of neutrons from the periodic table alone.

Answer:

a. 17 c. 17 b. 74 d. 52 2. No. The periodic table gives atomic number and atomic mass (average of isotopes). Isotopes have different neutron - numbers, so exact neutron number cannot be determined from the periodic table.
