Physical science chapter 5 review
Ionic bond
A chemical bond resulting from the attraction between oppositely charged ions. (normally metal, nonmetal)
if 2 sulfur atoms bond with each other, will they form a single bond or a double bond? is it non-polar or polar?
Double bond, will also be non-polar
polar molecules
Molecules that have an unequal distribution of charges
must atoms of one element always bond with atoms of a different element in order to become stable?
No, same elements can bond together ( Ex. :oxygen)
nonpolar bond
a covalent bond in which electrons are shared equally
What is a chemical bond?
an electrostatic attraction that exists between atoms due to the sharing or exchanging of valence electrons
polar covalent bond
atoms having diff. electronegativities share electrons unequally
describe a metallic bond
attraction between metal atoms and their shared pool of electrons / low electronegativity
molecule
covalent bonding of 2 or more atoms, smallest individual unit of a covalent compound
will two iodine atoms form an ionic or covalent bond?
covalent; electronegativity is the same
(true or false) A triple bond holds 3 atoms together
false; holds 3 Pairs of atoms
(true or false) Compounds often have physical and chemical properties that are similar to those of the elements of which they are made.
false; very different
what is used to represent the ratio of ions in a group of ionically bonded atoms?
formula unit
if 2 atoms have very different electronegativities, will they form an ionic bond or a covalent bond?
ionic bond
what does a chemical formula tell about a compound?
it identifies the compound, the element, and how atoms of each element
Multiple bond
sharing multiple electrons to make a double or triple bond
what does an oxidation state indicate about an element
shows the electric charged gained or lost by that element when it forms a compound / gains or losses in electrons
Polarity
unequal distribution of electric charge
Covalent bond
when atoms must share electrons due to having similar electronegativities.
