For each row in the table below, decide whether the pair of elements will form a molecular compound held together by covalent chemical bonds. If the elements will form a molecular compound, check the box and enter the chemical formula and name of the compound. (If the elements will form more than one molecular compound, use the compound with the fewest total number of atoms.) You may assume all chemical bonds are single bonds, not double or triple bonds. element #1 element #2 carbon iodine hydrogen iodine potassium nitrogen element pair will form a molecular compound molecular compound chemical formula 0 0 П name 0 0 ☐ Ś

Determine whether the following atoms will form an ionic compound or a molecular compound, and give the formula of the compound. (a) 2 bromine  (b) carbon and oxygen

Octet rule For elements in neutral molecules, the number of bonds needed to achieve an octet follows a trend by group, as shown in the following table: Group 4A 5A 6A 7A Number of bonds 4 3 2 1 Number of lone pairs 0 1 2 3 Part A Draw the Lewis structure for SiCl2 Br2. To add the element Si, either double click on any atom and type the element symbol, or access a periodic table of elements from the More button. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
