Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

Pattern of separation of charge in electronegativity - ️️The greater the difference between the electronegativities of two bonded atoms, the greater the separation of charge will be in the bond What determines the strength and length of a covalent bond - ️️More shared electron pairs increases bond energy and shortens the length between atoms Importance of Biochemical Reactions - ️️-Help establish and maintain a stable optimal internal environment to preserve life -Maintain Hom...

"The association of nonpolar groups or compounds with each other in aqueous systems, driven by the tendency of the surrounding water molecules to seek their most stable (disordered) state" is an example of: Correct Answer-*Hydrophobic interaction Which of the following is true about the chemical bonds found in proteins and nucleic acids? Correct Answer-*Atoms having a small difference between their electronegativities are more likely to form covalent bonds. The maximum number of bonds th...

Valency correct answers How many electrons the atom need to fill shell - Shell 1: 2e- - Shell 2: 8e- - Shell 3: 18e- Covalent bonds correct answers - Sharing of electrons between atoms of the same or different element Compound correct answers - combo of 2+ different elements Electronegativity correct answers - Atoms attraction for e- in covalent bond (EX: H2O) - Determines the distribution of e- w/in a covalent bond - higher value = stronger attraction of electrons EX: O = 3.5...
