Analyze the symbol of Niobium. What is TRUE of the atomic number, mass number, number of protons and number of neutrons? Select the 4 answers that apply.
The symbol of Niobium is Nb.
The atomic number of Niobium is 41, which means it has 41 protons in its nucleus.
The mass number of Niobium is typically around 92, which is the sum of the protons and neutrons in its nucleus. However, the mass number can vary slightly due to the presence of isotopes.
The number of protons in Niobium is 41.
The number of neutrons in Niobium can be calculated by subtracting the number of protons (41) from the mass number (typically around 92). Thus, the number of neutrons in Niobium is typically around 51.
Therefore, the 4 answers that apply are:
- Atomic number: 41
- Number of protons: 41
- Mass number: around 92
- Number of neutrons: around 51
a
The atomic number of niobium is 41.
b
The atomic number of niobium is 93.
c
The mass number of niobium is 93.
d
The mass number of niobium is 41.
e
Niobium has 52 neutrons.
f
Niobium has 93 neutrons.
g
Niobium has 41 neutrons.
h
Niobium has 41 protons.
i
Niobium has 52 protons.
j
Niobium has 93 protons.
The correct answers are:
a. The atomic number of niobium is 41.
d. The mass number of niobium is 41.
e. Niobium has 52 neutrons.
h. Niobium has 41 protons.
