Definitions
The distance from the center of nucleus to the atom's valence electrons.
What is atomic radius?
This type of compound has at least one metal and one nonmetal.
What is an ionic compound?
When drawing a Lewis structure with more than two elements, this element goes in the center of the structure.
What is the element with the most unpaired electrons or the least electronegativity.
The most electronegative element.
What is fluorine?
The prefix used to indicate that there are five of the same atom in a covalent compound.
What is penta?
The name of the structures that form spheres around fats or oils mixed in water.
What are micelles?
This type of compound is composed of nonmetals and sometimes metalloids.
What is a covalent compound?
When drawing a Lewis structure, a shared pair of electrons is replaced with this.
What is a line?
The relationship between the number of protons and electronegativity can be described as this.
What is proportional? (The more protons, the more the electronegativity.)
This type of compound dissolves well in water.
What is polar compound?
A measure of how strongly atoms attract electrons in a covalent bond.
What is electronegativity?
In this type of molecule electrons are shared.
What is a covalent compound?
When drawing the Lewis structure for oxygen in its natural form, the structure would look like this.
What is two oxygen atoms with a double bond?
The relationship between size of an atom and electronegativity can be described as this.
What is inversely proportional? (The larger the atom, the less electronegative.)
The part of the soap molecule that mixes with water.
What is ionic (polar) head?
A molecule with a polar end and a nonpolar end.
What is a soap molecule?
This type of molecule that has an uneven distribution of electrons, resulting in slight charges within the molecule itself.
What is a polar covalent molecule?
The VSEPR theory says that the shape of a molecule is based on the _________ between the valence electron pairs found in the molecule.
What is repulsion?
The electronegativity trend on the Periodic Table from left to right can be described as this.
What is increasing electronegativity?
Nitrogen forms a homonuclear diatomic molecule with this type of bond.
What is a triple bond?
Light scattering by particles in a colloid is known as this effect.
What is Tyndall effect?
This type of molecule has an even distribution of electrons resulting in no charges within the molecule itself.
What is a purely covalent molecule?
The geometric shape of the water molecule.
What is bent?
These two properties determine the electronegativity of an element.
What is atom size and and number of protons?
Name the elements that form homonuclear diatomic molecules.
