Make the central atom in your Lewis structure follow the octet rule if possible. a) There are 0  bonds and 4  bonds in one molecule or ion of this substance. b) There are 3  bonds and 1  bonds in one molecule or ion of this substance. c) There are 4  bonds and 1  bonds in one molecule or ion of this substance. d) There are 4  bonds and 4  bonds in one molecule or ion of this substance. e) There are 4  bonds and 0  bonds in one molecule or ion of this substance.

Write a Lewis structure for each of the following molecules. H3COH (carbon and oxygen are both central)         Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.

Write a Lewis structure for each of the following molecules. H2O2 Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.

Compare between the following. 2- ionic bond and metallic bond. 3- Sigma and pi bond . 4-(I) Group and (VIlA) Group.

Which of the following statements regarding covalent bonding is incorrect? All atoms in a Lewis structure will have eight electrons around their element symbol. Covalent bonds occur between two nonmetals. Two atoms may share up to three pairs of electrons. Carbon typically forms four bonds. The elements which exist as diatomic molecules do so in order to achieve a stable electron configuration.
