how many electrons should be in the first ring of a zinc atom?\n1\n2\n3\n4
Answer
Answer:
B. 2
Explanation:
Step1: Recall electron - shell rules
The first electron shell (n = 1) can hold a maximum of 2 electrons according to the 2n² rule (where n is the principal quantum number). For n = 1, 2n²=2×1² = 2. This rule applies to all atoms, including zinc. So, the first ring (shell) of a zinc atom has 2 electrons.
