This rule states that to become stable, an atom has to have 8 electrons in its valence shell. One of the ways by which an atom can achieve this is by sharing their electrons. When electrons are shared between atoms, a covalent bond is formed....
If a hydrogen atom bonds with another hydrogen atom( H-H), is this a hydrogen bond or covalent bond?What type of chemical bond holds the atoms together within a water molecule? a. ionic bond b. polar covalent bond c. nonpolar covalent bond d. coordinat...
Which of the following compounds contains a polar covalent bond? A) NaF B) HCl C) MgO D) O_2 Which of the following molecules is polar? (a) NO_2. (b) CO_2. (c) BF_3. (d) SF_6. (e) CCl_4. Which of these three compounds are covalent? a. CH3Cl b...
Ionic compounds are compounds consisting of ions. Two-element compounds are usually ionic when one element is a metal and the other is a non-metal. Examples include:sodium chloride: NaCl, with Na+and Cl-ions. ... magnesium oxide: MgO, with Mg2+and O2-ions. Is NH4NO3 ionic? Ammonium nit...

First, instead of combining a Group 1A and 7A element with just a single electron donated, elements from Group 2A and 6A can also form ionic bonds. In these cases, the Group 2A element donates two electrons to the 6A element. Magnesium oxide, MgO, is one such example, where magnesium do...
What is the name of the ionic compound MgO? What is the name of the compound with the formula Al2O3? Identify the formula and name of the cation and anion. What type of compound can have both an empirical formula and a molecular formula? a. ionic b. both ionic and cova...
MGO forms spontaneously as a glycolytic by-product and is detoxified by the sequential action of glyoxalases 1 and 2. It forms covalent adducts with cysteines, arginines, and lysines (hemithioacetals with cysteines and aminocarbinols with arginines and lysines) and also forms imidazolidines ...
Which of the following is the weakest bond? a. a triple bondb. a double bondc. a single bondd. They are all the same strength. Bond Order: Bond order is responsible for the strength of a bond. The higher the bond order of the...
and can be classified as either ionic or covalent. An ionic compound is formed by a cation and anion which are positively and negatively charged, respectively. On the other hand, a covalent compound is formed between nonmetallic elements whose atoms share electrons to form a covalent bond. ...
