Step 1:I'll solve this problem step by step, following the precise LaTeX formatting guidelines:
Step 2:: Identify the Atomic Components
- Number of electrons: $$3
Let's break down the atomic structure of the lithium atom:
Step 3:: Calculate the Atomic Number
Z = 3
The atomic number is equal to the number of protons:
Step 4:: Calculate the Mass Number
A = 3 + 4 = 7
The mass number is the sum of protons and neutrons:
Step 5:: Determine the Atomic Notation
Using the standard atomic notation $$^{A}_{Z}X$$, where X is the chemical symbol:
^{7}_{3}Li
Step 6:: Determine the Charge
Net charge: $$0$$ (neutral atom)
Number of electrons: 3
Final Answer
- Atomic Number: 3 - Mass Number: 7 - Notation: ^{7}_{3}Li - Charge: Neutral (0)
