- What type of bond forms when electrons are transferred from one atom to another?
Show answer
An ionic bond- What type of bond forms when atoms share electron pairs?
Show answer
A covalent bond- What type of bonding is characterized by a "sea of delocalized electrons" shared among many atoms?
Show answer
Metallic bonding- What property describes an atom's ability to attract electrons in a chemical bond?
Show answer
Electronegativity- What is a nonpolar covalent bond?
Show answer
A covalent bond in which electrons are shared roughly equally between atoms of similar electronegativity- What is a polar covalent bond?
Show answer
A covalent bond in which electrons are shared unequally due to a difference in electronegativity between atoms- What theory predicts molecular geometry based on minimizing repulsion between electron pairs around a central atom?
Show answer
Valence shell electron pair repulsion (VSEPR) theory- What molecular geometry results from a central atom with four bonding pairs and no lone pairs?
Show answer
Tetrahedral- What molecular geometry results from a central atom with three bonding pairs and one lone pair?
Show answer
Trigonal pyramidal- What molecular geometry results from a central atom with two bonding pairs and two lone pairs?
Show answer
Bent (angular)- What molecular geometry results from a central atom with three bonding pairs and no lone pairs?
