Chapter 5: Covalent Compounds and Their Chemistry Flashcards
what is a homonuclear diatomic?
A molecule consisting of two atoms of the same element
what is a covalent bond?
A chemical bond that is made by sharing electrons
True/false: hydrogens, ideal electron configuration consists of two valence electrons, not eight
true
what are covalent compounds?
A compound who’s elements are held together with covalent bonds
True/false: covalent compounds do not contain metals
true
what is atomic radius?
The distance from the center of the nucleus to the atoms valence electrons
True/false: as you travel up the periodic table, and to the right, the atomic radius increases
false
what is electronegativity?
A measure of how strongly atoms attract electrons in a covalent bond
True/false: as you travel up the periodic table, and the right electronegativity increases
True
what is a polar covalent bond?
A covalent bond in which the electrons are not shared equally
what is a polar covalent molecule?
A molecule that has an uneven distribution of electrons resulting in slight charges within the molecule itself
True/false: a polar covalent molecule must have polar covalent bonds
True
what is a purely covalent bond?
A covalent bond in which electrons are shared equally
what is a purely covalent molecule?
Molecule that has an even distribution of electrons resulting in no charges within a molecule itself
True/false: a polar covalent molecule must have polar covalent bonds that don’t pour equally in all directions
True
