please mark me as brainliest
The Main Answer is: 1.) Sodium
2.) 11 electrons
3.) L shell
4.) 8 electrons
Given: A Lewis dot structure of an atom
To Find: 1. Identify the element.
2. How many electrons are there?
3. Name the second cell of the atom.
4. How many electrons are there in this shell?
Solution:
1.)
- The given structure of the atom has been labeled as "Na".
- This is the chemical formula for Sodium metal.
- Also, there are a total of 11 electrons present in the atom.
- As the no. of electrons = no. of protons = 11
- The atomic no. (no. of protons) for the given atom = 11
- And the element with atomic no. 11 is Sodium.
2.)
- As mentioned above, on counting, one can find that the number of electrons in the given atom = 11
3.)
- In general, the shells of any atom are labeled as K, L, M, N, and so on; where K = 1st shell, L = 2nd shell, and so forth.
- Therefore, here, the second shell of the atom is the L shell.
4.)
- In the L shell, in this atom, there are 8 electrons and it has reached its maximum capacity.
- The maximum no. of electrons that a shell can accommodate = 2n²; where n = shell number, in this case, n = 2.
- ∴ Max capacity = 2 × 4 = 8.
Therefore, the final answers are: 1.) Sodium
2.) 11 electrons
3.) L shell
4.) 8 electrons
