can you help me with this
For the following isotope, give its atomic number, mass number, number of protons, and number of neutrons.
ytterbium-169
Atomic number
Mass number
Number of protons
Number of neutrons
To find the atomic number and mass number of ytterbium-169, we can break it down as follows:
1. The atomic number of an element is the same as the number of protons in the nucleus. Since ytterbium-169 is a specific isotope of ytterbium, the atomic number is 70.
2. The mass number of an isotope is the sum of the number of protons and neutrons in the nucleus. For ytterbium-169, the mass number is 169.
3. The number of protons in ytterbium-169 is the same as the atomic number, which is 70.
4. To find the number of neutrons in ytterbium-169, you subtract the number of protons (atomic number) from the mass number:
Number of neutrons = Mass number - Atomic number
Number of neutrons = 169 - 70
Number of neutrons = 99
Therefore, for ytterbium-169:
Atomic number = 70
Mass number = 169
Number of protons = 70
Number of neutrons = 99
