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.
