Here's the information for Lithium (Li) based on the data you've provided:
-
Atomic Number: 3 (This is the number of protons)
-
Atomic Mass: 6.941 (This is the average mass of an atom of Lithium measured in atomic mass units)
-
Number of Protons: 3 (The atomic number indicates the number of protons)
-
Number of Electrons: 3 (In a neutral atom, the number of electrons equals the number of protons)
-
Number of Neutrons: To calculate the number of neutrons, you can use the formula:
\[ \text{Number of Neutrons} = \text{Atomic Mass (rounded)} - \text{Number of Protons} \]
For Lithium, rounding the atomic mass (6.941) gives approximately 7:
\[ \text{Number of Neutrons} = 7 - 3 = 4 \]
So, summarizing:
- Atomic Number: 3
- Atomic Mass: 6.941
- Number of Protons: 3
- Number of Neutrons: 4
- Number of Electrons: 3
