An atom hasn= 1andn= 2levels filled. How many electrons does the atom ...
Number of electrons in nth orbit is given by 2n2
∴ total electrons is = 2(1)2 + 2(22)
= 2 + 8 = 10
The correct answer is: 10
∴ total electrons is = 2(1)2 + 2(22)
= 2 + 8 = 10
The correct answer is: 10

An atom hasn= 1andn= 2levels filled. How many electrons does the atom ...
Answer:
To determine the number of electrons in an atom, we need to know the number of levels filled in the atom. In this case, the atom has 1 level filled (the first level) and 2 levels total.
Explanation:
1. Understanding atomic structure:
- An atom consists of a nucleus, which contains protons and neutrons, surrounded by electron shells or energy levels.
- Each electron shell has a maximum capacity for a certain number of electrons.
2. Filling electron shells:
- The first electron shell (n=1) can hold a maximum of 2 electrons.
- The second electron shell (n=2) can hold a maximum of 8 electrons.
- The third electron shell (n=3) can hold a maximum of 18 electrons, and so on.
3. Determining the number of electrons:
- In the given question, the atom has 1 level filled (n=1) and a total of 2 levels (n=1 and n=2).
- Therefore, we can conclude that the atom has filled its first level completely with 2 electrons.
- Since the first level can hold a maximum of 2 electrons, there are no more electrons in the second level.
- Thus, the atom has a total of 2 electrons.
Summary:
- The atom described in the question has 1 level filled completely and a total of 2 levels.
- The first level can hold a maximum of 2 electrons, so the atom has 2 electrons in total.
- Therefore, the correct answer is option 'B' (10).
