What is a Lewis dot symbol?

Answer 1

To figure out the Lewis dot structure, look at the valence electrons. These are electrons in the outermost shell.

1. Figure out the group it is in at the Periodic Table or figure out its configuration electron.. *v=valence electrons

Alkali Metals: 1v*

Alkaline Earth Metals: 2v

Groups 3-5, 7-10, 12: 2v

Groups 6 and 11: 1v

Group 13: 3v

Group 14: 4v

Group 15: 5v

Group 16: 6v

Group 17: 7v

Group 18: 8v

Magnesium: Group 2, Alkaline Earth Metals: 2 valence electrons

Electron Configuration: 1s2 2s2 2p6 3s2

Shell Electrons: 2, 8, 2

2. The valence electrons are the number of dots you draw around the chemical symbol, in this case, magnesium, or Mg.

So, the symbol is 2 dots around Mg.

Answer 2

Judging from the valence shell structure (in which I could include also the 3d- orbital electrons, because the energy difference between 3d and 4s is so small), I would say 8 dots for 8 electrons. (3d orbital electrons excluded only 2 dots, which would make f.ex FeCl3 Lewis structure even more difficult to explain)

Answer 3

Lewis structures (also known as Lewis dot diagrams, electron dot diagrams, and electron dot structures) are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently - bonded molecule, as well as coordination compounds. The Lewis structure was named after Gilbert Newton Lewis, who introduced it in his 1916 article The Atom and the Molecule. They are similar to electron dot diagrams in that the valence electrons in lone pairs are represented as dots, but they also contain lines to represent shared pairs in a chemical bond (single, double, triple, etc.).

Answer 4

A Lewis dot symbol is a representation of an atom that shows the number of valence electrons around the element. This is done by using dots around the symbol to represent the electrons in the outermost energy level of the atom. It helps visualize bonding and predict chemical reactivity.

here u go!!! good luck with chem :]

Answer 6

:O:

..

this would have a resonance structure too. 18 electrons total. 1 single bond. 1 double bond. 6 lone pairs

Answer 7

the Lewis dot diagram is a table used for the elements, and it shows you how many valence electrons there are. ;)
