Uses of your element
Living things need ----- to breathe. ----- gas is used a lot in the steel industry. It is also used for cutting metals.
Physical Properties
Properties that can be observed or measured without changing the chemical nature of the substance. Ex. Color, Density, Volume, Mass, Boiling Point, Melting Point.
Chemical Properties & the types of Elements that it interacts with
Properties that must show a change in a substance or compound's chemical format. They interact with substances like air, water, and heat.
Atomic Mass
The ------- of an atom is the average mass of atoms in one element. Oxygen's ----------- is 15.9994.
Density
a measure of mass per unit of volume. D= M/V. Ex. The ------- of oxygen is 0.001429 grams per cubic centimeter. 0.001429 g/cm3.
Color
a property of a substance, due to the absorption of light rays. Ex. Oxygen is.......--- ----IT'S A GAS
Chemical Symbol
an abbreviation of one or two letters that represent a chemical element. For example, Oxygens -----------is O.
A nonmetallic element
an element that cannot control heat or electricity well. There are 17. Ex. Oxygen is a ------ Element
Atomic #
how many protons are in the atom's nucleus. For example, Oxygen's ------- is 8. Oxygen's -------- is 8.
Electrons
negatively charged subatomic particles. They can be free or attached to the nucleus. There are 8 ------- in Oxygen.
Electron Configuration
organized groups of electrons and orbitals of a molecule or atom. For example, Oxygen's -------- is [He] 1s2 2s2 2p4.
Neutrons
subatomic particles that are found in the nucleus of every atom. They have no electric charge, they are neutral. Ex. There are 8 ------ in Oxygen.
Electrons
subatomic particles that are negatively charged, and free or attached to the nucleus. Ex. There are 8 ------- in Oxygen.
Protons
subatomic positively charged particles that are found in the nucleus of every atom. They have a positive charge, and the same number of particles as the electrons. Ex. Oxygen has 8 --------.
Atomic Nucleus
the small part in the middle of an atom. It has a positive electric charge and which the mass of the atom is concentrated.
Boiling Point
the temperature where a liquid gets so hot to the point where the pressure causes the liquid to boil. Ex. Oxygen's-------- is -297.3 degrees F.
Melting Point
the temperature where a solid will melt to become a liquid. Ex. Oxygen's -------- is -361.8 degrees Fahrenheit, or -218.8 degrees celsius.
Freezing Point
the temperature where liquids will freeze and become solids. Ex. Oxygens -------- is -361.8 degrees Fahrenheit, or 218.8 degrees celsius.
Name
what the element is called. For example, the n---- of my element is Oxygen.
# of Orbitals
zones in the atom where you have a high chance of finding the electron. Electrons are fixed within ------. Ex. an electron cloud having an energy state described by given values of the n, ℓ, and mℓ Quantum numbers.
Fun Facts about your element
Animals and plants require oxygen for breathing. Oxygen gas is colorless and odorless. Liquid and solid oxygen is pale blue. ⅔ of the mass of the human is oxygen.
