Question
Nobel gases are examples of elements that follow the octet rule. What does this rule mean? How would you describe the difference between ionic and covalent bonding? A third category of chemical bonding is which describes the difference in electronegativity between atoms with a compound that share electrons. Understand the nomenclature of ionic compounds. Calculate the number of moles in 1.8 g of CaCl_2. What are the 4 major types of chemical reactions. Find and illustrate examples. Stoichiomctry is the study of.... For stoichiometric measurements to be accurate it is first important to the chemical reaction written. Since most reactants are in solution and reactions occur in aqueous environments it is important to define molarity.... Given 34 g of NH_3 and 32 g of O_2, what is the mass of the product NO. Balance the following equation then calculate: NH_3 + O_2 rightarrow NO + H_2O If given 2.6 moles of KCI, how many grams of AgCI is expected to be produced? AgNO_3 + KCI AgCI + KNO_3 In the reaction above, if 2.6 moles of KCI were to react with 8.5 moles of AgNO_3, what is the mass of the product and which reactant would be limiting? Under constant temperature, a pressure of 12 torr and a volume of 8 L, what is the new pressure if the volume decreased to 6 L?Explanation / Answer
29 noble gases are examples of elements that follow the octet rule . what does this rule mean?
octet control, which expresses that electron exchange or electron sharing continues until a molecule has gained an octet of electrons (i.e., the eight electrons normal for the valence shell of a honorable gas iota). At the point when finish exchange happens, the holding is ionic..
The octet control is a synthetic dependable guideline that reflects perception that molecules of primary gathering components tend to consolidate in a manner that every iota has eight electrons in its valence shell, giving it an indistinguishable electronic setup from a respectable gas. The lead is particularly material to carbon, nitrogen, oxygen, and the incandescent light, additionally to metals, for example, sodium or magnesium.

Difference between ionic and covalent bonding
Covalent Bonds
Ionic Bonds
Formation
A covalent bond is framed between two non-metals that have comparable electronegativities. Neither one of the atoms is sufficiently solid to draw in electrons from the other. For adjustment, they share their electrons from external atomic circle with others.
An ionic bond is framed between a metal and a non-metal. Non-metals(- ve particle) are "more grounded" than the metal(+ve particle) and can get electrons effortlessly from the metal. These two inverse particles pull in each other and frame the ionic bond

31 A THIRD CATEGORY OF CHEMICAL BONDING coordinate covalent bond WHICH DESCRIBES THE DIFFERENCE IN ELECTRONEGATIVITY BEYWEEN ATOMS WITH COMPOUND THAT SHARE ELECTRONS
A co-ordinate bond (likewise called a dative covalent bond) is a covalent bond (a mutual combine of electrons) in which both electrons originate from a similar molecule.
