Lithium
6.94
A. Atomic number. 1. 3. 6.94. 4
B. Atomic mass. 1. 3. 6.94. 4
C. Number of electrons. 1. 3. 6.94. 4
D. Number of protons. 1. 3. 6.84. 4
E. Number of neutrons. 1. 3. 6.94. 4
F. Valence. 1. 3. 6.94. 4

Answer 1

Based on the information provided about lithium (Li) with an atomic number of 3 and an atomic mass of approximately 6.94, here are the answers for each category:

A. Atomic number: 3
B. Atomic mass: 6.94
C. Number of electrons: 3
D. Number of protons: 3
E. Number of neutrons: 4 (calculated as atomic mass - atomic number, which is 7 - 3 = 4)
F. Valence: 1 (lithium has one electron in its outer shell, giving it a valence of 1)

So the complete answers would be:

• A: 3
• B: 6.94
• C: 3
• D: 3
• E: 4
• F: 1
