Intro and Matter
The study of the composition, structure & properties of matter, the changes it undergoes, including energy changes.
What is chemistry?
Visible light, X-rays, infrared radiation, and radio waves all have the same __________.
What is frequency?
The “Father of the Modern Periodic Table” who arranged the elements in order of increasing atomic mass.
Who is Mendeleev?
The transfer of electrons from metals to nonmetals.
What is ionic bonding?
The sharing of valence electrons between nonmetals.
What is covalent bond?
The property that can only be observed by changing the composition of the material.
What is the chemical property?
This principle states that it is impossible to determine both the position and velocity of an electron or any other particle at the same time and helped lay the groundwork for the modern quantum theory.
What is the Heisenberg Uncertainty Principle?
This law states that when the elements are arranged by increasing atomic number, there is a periodic repetition of their chemical and physical properties.
What is Periodic Law?
The simplest ratio of elements in an ionic compound.
What is Formula Unit?
An uneven distribution of charge.
What is polar bond?
The scientific law that states the total amount of mass and energy is conserved.
What is the Law of Conservation of Mass and Energy?
The effect when light of a certain frequency strikes a metal surface and ejects electrons.
What is the photoelectric effect?
This is half the distance between the two nuclei of an atomic model.
What is atomic radius?
Something ionic compounds do not do in solid form.
What is conduct?
When drawing Lewis structures, you always draw these first.
What are unshared pairs?
The formation of solid particles out of solution containing the dissolved substance.
What is crystallization?
Atoms are excited when they have a higher potential energy and return to the _________ state when they emit a photon.
What is ground?
The energy given off when a neutral atom (in the gas phase) gains an extra e- to form a negatively charged ion.
What is electron affinity?
When naming ionic compounds, everything in the d block as well as Tin (Sn) and Lead (Pb) and not including Zinc (Zn) and Silver (Ag) need this.
What is a Roman numeral?
Molecules adopt the shape that does this to the electron pair repulsiones.
What is minimizes?
This process separates the components of a mixture based on the ability of each component to travel or be drawn across the surface of material.
What is chromatography?
The element besides Copper with an exception for electron configuration in the first 40 elements.
What is Chromium?
The tendency for an atom to attract e- to itself when it is chemically combined with another element.
What is electronegativity?
When naming acids, you always start with this element.
What is Hydrogen?
A single bond has this amount of energy compared to the double and triple bonds.
What is least?
