6 Questions
How are valence electrons defined?
The electrons in the outermost shell of an atom
How is a Lewis structure of an atom typically represented?
By writing the symbol of the atom and drawing dots around it to represent valence electrons
True or false: A Lewis structure shows the distribution of all electrons in an atom or molecule, not just the valence electrons.
False
What determines the number of valence electrons for representative elements?
The group number on the periodic table
True or false: The number of valence electrons for representative elements is equal to the period number on the periodic table.
False
True or false: To draw the Lewis structure of an atom, you only need to write the symbol of the atom and draw dots to represent the valence electrons.
