Answer:
a. Yes, both W and Y have the same atomic number. Since the atomic mass equals the sum of protons (which is the atomic number) and neutrons, both W and Y have different numbers of neutrons, making them isotops of each other.
b. Both W and Y have the same atomic number, making both the same element. Therefore they have the same chemical properties.
c. W: 29 protons, 34 neutrons, 29 electrons
Y: 29 protons, 36 neutrons, 29 electrons
Step-by-step explanation:
a. Yes, both W and Y have the same atomic number. Since the atomic mass equals the sum of protons (which is the atomic number) and neutrons, both W and Y have different numbers of neutrons, making them isotops of each other.
b. Both W and Y have the same atomic number, making both the same element. Therefore they have the same chemical properties.
c. W: 29 protons, 34 neutrons, 29 electrons
Y: 29 protons, 36 neutrons, 29 electrons
Remember: mass number = protons (atomic #) + neutrons
