what type of bond shares electrons
covalent
what bond transfers electrons from one atom to another
ionic
what type of covalent bond shares electrons equally amongst two atoms
non-polar covalent
what type of covalent bond shares electrons unequally
polar covalent
the attractive force that an atom exerts on an electron is known as
electronegativity is the
electrons will be drawn ____ the more electronegative atom
towards

polar covalent molecule diagram
ionic bond molecule diagram
a charged atom or group of atoms is known as an
ion
a positive ion is called
cation
a negative ion is called
anion
when does a redox reaction occur
when one atom loses or gives up an electron to another atom
an interaction between an H atom that is covalently bonded to an electronegative atom and the unbonded electrons of a second electronegative atom is known as a
hydrogen bond
hydrogen bond diagram
Which of the following solutions would have the highest concentration of hydrogen ions (H+)?
a. Water with a pH of 7
b. Sodium bicarbonate with a pH of 9
c. Beer with a pH of 4
d. Sodium hydroxide with a pH of 1
C
the difference between water and sodium bicarbonate is 2 pH scale points. This means that sodium bicarbonate is 2/10/100 times more acidic/basic/neutral than water
100, basic
