Atomic structure
What is a energy level?
Energy levels are what surround the nucleus. This is where the electrons are located
Atomic mass
Average mass of all isotopes of that element. (In top right corner usually a decimal.)
Metal
Any chemical element that is an effective conductor of electricity and heat can be defined as a metal. Atoms inside of a metal quickly lose electrons in order to make positive ions or cations.
Reactivity
Reactivity is the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy. Reactivity needs 8 full electrons.
Renewable resources
Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
What is an ion?
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Atomic number
Atomic number of protons usually on the left top corner
Nonmetals
a chemical element (as boron, carbon, or nitrogen) that lacks the characteristics of a metal and that is able to form anions, acidic oxides, acids, and stable compounds with hydrogen. Nonmetals like to gain electrons to form anions to have a fully stable octet.
Covalent bond
covalent bonds form when electrons are shared between two nonmetals.
Positives and negative of renewable energy
One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water.
What is how to determine number of each particle: Protons, Neutrons, Electron
The number of protons in the nucleus is equal to the atomic number. The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom is equal to the sum of the number of protons and neutrons in the nucleus.
Mass number
the total number of protons and neutrons (together known as nucleons) in an atomic nucleus.
Metalloid
an element whose properties are intermediate between those of metals and solid nonmetals. They are electrical semiconductors.
Ionic bond
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.
Define non renewable resources
Unon-renewable resource is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames.
What is a isotope
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Groups
a column of elements in the periodic table of the chemical elements. Y’all way on the periodic table.
Noble gasses
The noble gases make up a group of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.
Lewis dot diagram
A Lewis structure is a drawing of a molecule that illustrates the connectivity of the compound, as well as identifying the lone pairs of electrons available for bonding with other molecules.
Positives of non renewable resources
main advantages of non-renewable energies is that they are abundant and affordable.
What is a valence electrons
valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
Periods
The periods are numbered 1 through 7 on the left-hand side of the table. Elements that are in the same period have chemical properties that are not all that similar. Usually wide/long way.
how many electrons does a full element need
8
What do you count to make your Lewis dot diagram
Valence electrons
Negatives of non renewable
According to the U.S. Energy Information Administration, non-renewable energy sources cannot be replenished in a short period.
