Compound that contains one carbon atom and two oxygen atom is named as carbon dioxide rather than dioxygen monocarbide and the reason for this has to be given. Concept Introduction: Molecular compound that contains only two nonmetallic elements in it is known as Binary molecular compound. Naming a binary molecular compound is similar to that of a binary ionic compound. A major difference is that the binary molecular compound contain numerical prefixes which gives the information about the number of atoms of same kind are present in it. For naming a binary molecular compound, the element that has lower electronegativity is given first and that is followed by a stem of the name of the nonmetal that is more electronegative and the suffix “-ide”. Numerical prefixes are added to both nonmetals to indicate the number of atoms present in it. Some binary molecular compounds have names that are no way related to the naming rules. They are common names that are given for the compounds before the systematic rule development. Chemical formula is a representation of the total number of same type of atoms that is present in the molecule. The chemical formula for binary compounds can be identified from the prefix that is present in the two words of the name of binary compounds. The prefix is put as number in subscript after the atomic symbol.

Given the pair of compounds,AlCl3 and CaCl2, which is more ionic and why ?

Covalent bonding involves the sharing of electrons between atoms. The number of covalent bonds an atom can form relates to the number of electrons it can share and still result in a neutral molecule. It is important to know how many bonds certain elements are most likely to form in order to draw structural formulas for molecules.

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure Is the proposed Lewis structure reasonable? O Yes. O No, it has the wrong number of valence electrons. はードー =N 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:* O Yes. No, it has the wrong number of valence electrons. 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:* O Yes. O No, it has the wrong number of valence electrons. The correct number is: | No, it has the right number of valence electrons but doesn't satisfy the octet rule. : Cl C : 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". O O
