newly discovered element Lm has 3 valence electrons. How many total valence electrons are in LmF3 molecule, a molecule that Lm forms with fluorine? Draw a valid Lewis Structure for the molecule LmF3 that Lm forms with fluorine and use your Lewis structure to determine the number of lone pairs of electrons around the central Lm atom in this molecule. What is the formal charge of Lm in LmF3? (Number and sign of formal charge) What is the hybridization of Lm according to the hybrid orbital model?

The formal charge is the "charge" an element would have in a molecule or ion if all of the bonding electrons were shared equally between atoms. We can draw three inequivalent Lewis structures for the arsenite ion , AsO33- . The concepts of formal charge and electronegativity can help us choose the structure that is the best representation.1. Assign formal charges to the elements in each of the structures below.Note: Count oxygen atoms starting from the left for each structure.

draw the lewis structure of ClO-3 following the octet rule. How many double bonds are present? How many lone pairs? What is the formal charge of Cl? What is the formal charge of O?

Recognising exceptions to the octet rule.

Decide whether this proposed Lewis structure is reasonable. proposed Lewis structure Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. : Z: : 0: N O C1: The correct number is: ☐ - No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* ☐ * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0". X

♥ Draw Lewis structures for each of the following. Use the DEN and the number of REDs around thecentral atom to select the type of bonds, the molecular shape, and type of molecule from the lists.♥ Do not put covalent bonds between metals and nonmetals♥ Put brackets around anions to show both charge and quantity.

Decide whether the Lewis structure proposed for each molecule is reasonable or not. molecule proposed Lewis structure BeH₂ :O || :0 || :F: :F: H- Be H Is this a reasonable structure? If not, why not? Yes, it's a reasonable structure. O No, the total number of valence electrons is wrong. The correct number is: O No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: O Yes, it's a reasonable structure. O No, the total number of valence electrons is wrong. The correct number is: O No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: 0 O Yes, it's a reasonable structure.

An incomplete Lewis structure is shown. The structure only shows the atom and how they are connected. The molecule has a bet charge of -1. Complete the Lewis structure giving all atoms full octets. If there is more than one way to do this, draw resonance structure showing all possibilities. If not, just draw one Lewis structure. Be sure to write in any non-Zero formal charges..
