Lewis Structure Indicating Molecular Geometry Lewis Structure Molecular Formula Electron Molecular Geometry Geometry IFS

I need help with this question because I stuggled with this homework

Please complete the last 4

Use Lewis theory to determine the formula for the compound that forms between each of the following pairs of elements. Ca and Te Express your answer as a chemical formula.   Mg and Br Express your answer as a chemical formula.   Na and S Express your answer as a chemical formula.   In and O Express your answer as a chemical formula.

Following is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.) O trigonal pyramidal shape, nonpolar O trigonal planar shape, nonpolar O tetrahedral shape, polar O trigonal pyramidal shape, polar O trigonal planar shape, polar

Provide the Lewis, structure, Molecule/Ion type (i.e. AX3E, AX5, etc), Molecular Geometry, bond angle (the ideal/pure bond angle, not the bond angle as affect by lone pairs), and Polarity (a 3-d representation with bond and molecular dipoles annotated) "Exclude IF5"

i wanna help to complete this table (lewis structure, molecular shap and polar or non polar) table in attachments.

Not sure what is wrong with the second half

Decide whether the Lewis structure proposed for each molecule is reasonable or not. proposed Lewis structure Is this a reasonable structure? If not, why not? molecule O Yes, it's a reasonable structure. :F: No, the total number of valence electrons is wrong. BF, The correct number is:| :F-B -F: O No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: L 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: U O Yes, it's a reasonable structure. :F: No, the total number of valence electrons is wrong. CIF, The correct number is:| .. Cl –F: No, some atoms have the wrong number of electrons around them. : F The symbols of the problem atoms are:U * If two or more atoms have the wrong number of valence electrons around them, just enter the chemical symbol for the atom as many times as…
