Answer:
Oxygen- 6
Calcium-2
Nitrogen-5
Aluminum-3
Flourine-7
Explanation:
A Lewis structure or dot electron structure is a representation of an atom in which the valence electrons on the outermost shell of the atom are represented as dots.
These dots show the number of valence electrons as well as the group to which the atom belongs in the periodic table.
The Lewis structure of an oxygen atom should have 6 dots drawn around the symbol
The Lewis structure of a calcium atom should have 2 dots drawn around the symbol Ca
The Lewis structure of a nitrogen atom should have 5 dots drawn around the symbol N
The Lewis structure of an aluminum atom should have 3 dots drawn around the symbol Al
The Lewis structure of a fluorine atom should have 7 dots drawn around the symbol F
- For Oxygen atom
The oxygen atom has 6 electrons in its outermost shell
Hence, the Lewis structure of an oxygen atom should have 6 dots drawn around the symbol
- For Calcium atom
The calcium atom has 2 electrons in its outermost shell
Hence, the Lewis structure of a calcium atom should have 2 dots drawn around the symbol Ca
- For Nitrogen atom
The nitrogen atom has 5 electrons in its outermost shell
Hence, the Lewis structure of a nitrogen atom should have 5 dots drawn around the symbol N
- For Aluminum atom
The nitrogen atom has 3 electrons in its outermost shell
Hence, the Lewis structure of an aluminum atom should have 3 dots drawn around the symbol Al
- For Fluorine atom
The fluorine atom has 7 electrons in its outermost shell
Hence, the Lewis structure of a fluorine atom should have 7 dots drawn around the symbol F
Hence,
The Lewis structure of an oxygen atom should have 6 dots drawn around the symbol
The Lewis structure of a calcium atom should have 2 dots drawn around the symbol Ca
The Lewis structure of a nitrogen atom should have 5 dots drawn around the symbol N
The Lewis structure of an aluminum atom should have 3 dots drawn around the symbol Al
The Lewis structure of a fluorine atom should have 7 dots drawn around the symbol F
