Ch.1
What is an element?
Anything on the Periodic Table
What is the chemical symbol for Carbon?
C
What is the charge of a Neutron?
Neutral or no charge.
What is a valence electron?
electrons in the outermost ring.
What functional group smells putrid?
COOH or Carboxyl group
What is matter?
Anything that has mass and takes up space, anything made of things on the periodic table.
What is a compound?
Name three subatomic particles
Protons, Neutrons, and Electrons
What is an ion?
A charged particle
What is the Octet rule?
When bonding atoms must gain, lose, or share so each gets 8 valence electrons.
What do you use to measure liquids?
Graduated cylinder
What is the periodic trend as we go top to bottom?
Reactivity increases
What atomic model says atoms can be divided into fluid and electrons?
Plum Pudding Model
Why do elements become Ions?
To have full valence shells or to look like a noble gas.
What happens in a covalent bond?
Electrons are shared to satisfy octet rule
What are 3 examples of proper lab safety?
Hair tied back, Closed toed shoes, Goggles, ETC.
What group/family is the most reactive?
Group 7A or the Halogens
Which scientist and experiment developed the nuclear model?
Rutherford and his Alpha Particles
What do we call positive ions?
Cations
What is the HONC 1234 Rule?
H=1 bond O=2 bonds N=3 bonds C=4 bonds
How do you calculate volume?
V=m/d
What is the Law of Conservation of Matter?
Matter neither created nor destroyed, so we must have the same number and type of atoms after the chemical change as were present before the chemical change.
What is an Isotope?
Same element with different number of Neutrons
What is the rule of zero charge?
When metals and non metals bond the charge must equal zero.
What is an Isomer?
molecules with the same molecular formula but a different structural formula?
