it tells us about the valence electrons in an atom. we need to know the valence electrons because they are the only ones that take part in chemical reaction.

A structure in which atomic symbols represent nuclei and inner-shell electrons and in which dots are used to represent valence electrons are called?
lewis dot
Does the Lewis dot structure represent the total number of electrons in the atom?
no. just the valence shell
What diagram shows the valence electron pattern of carbon Adams?
A diagram of a typical carbon atom would show a nucleus comprised of 6 protons and 6 neutrons. It would also have two electrons in the first energy level, then 4 electrons in the second, or valence energy level (1s22s22p2.)
The Roman numeral at the top of a column on the periodic table indicates the number of?
They represent the valance electrons in each element. Roman numerals do no represent the valence electrons but it is the group number given by mendeleef.
Describe how electron dot diagrams can be used and why they are helpful?
Electron dot diagrams are used to represent electron sharing and can easily show how elements bond. The dots represent valence electrons and makes it easier to show students.
What do the dots in a Lewis structure represent?
Valence electrons.
What do the electrons in an electron dot structure represent?
It represents the number of valence electrons in the atom.
What does the blocks represent?
For the elements in the s-block, the valence electrons are filled in the s orbital.
A structure in which atomic symbols represent nuclei and inner-shell electrons and in which dots are used to represent valence electrons are called?
lewis dot
Is each dots in an electron dot diagram used to represent valance electrons?
Yes, the dots in an electron dot diagram represent valence electrons.
Does the Lewis dot structure represent the total number of electrons in the atom?
no. just the valence shell
In an periodic table dots around an elements symbol indicate the number of valence electrons in an atom?
yes, the number of dots represent the number of valence electrons in the periodic table.
The Lewis dot symbol for the a lead atom is?
Pb with 4 dots around it to represent its 4 valence electrons.
What are dot diagrams used to represent?
Outer electrons
How do valence electrons relate to group number?
The group numbers represent the number of valence electrons. 1 has 1, 2 has 2. Then, skipping over transition metals, 13 has 3, 14 has 4, etc.
What does each dots in an electron dot diagram represent?
The dots are the valence electrons in the outermost shell of an element. The number of valence electrons are the group number of the element (H=1, O=6, C=4 etc.)
Why is valence important in the understanding chemical bonds?
Valence bond and molecular orbital theories are used to explain chemical bonding A single covalent bond represent the sharing of two valence electrons (two different atoms). Ionic bonding is typically transfer of electron(s) between a metal and a nonmetal
