I believe propane burns to form water vapor and carbon dioxide
True
Explanation:
In the electron dot notation, the two dots on Be represents valence electrons in the s-sublevel.
The electron dot notation is also known as lewis dot structure.
This notation shows only the chemical symbol surrounded by dots to represent the valence electrons.
The dots are arranged at the four sides of the symbol in pairs called lone pairs. The unpaired ones are the odd electrons.
For Be, the structure is 1s² 2s²
The 2s sublevel is in the outermost/valence shell and it is made up of two electrons.
It is correct to say that the two dots on Be denotes the valence electrons in the s-sublevel.
