The Atom
The center of an atom.
What is the nucleus?
A scale in which the numbers range from 0 to 14.
What is the pH scale?
Due to polarity, water is attracted to other water molecules.
What is cohesion?
The two types of bonding that we discussed.
What are ionic and covalent bonding?
The periodic table is arranged by the increasing amount of this number.
What is the atomic number?
The subatomic particles of an atom.
What are electrons, protons and neutrons?
These substances contain a higher concentration of H+.
What are acids?
Water loving. Water fearing.
What is hydrophilic and hydrophobic.
When elements share electrons.
What is covalent bonding?
These allow us to determine the valence electrons for the elements.
What are groups?
When two substances have the same amount of protons but different neutrons.
What is an isotope?
These substances contains a higher concentrations of OH-
What are bases?
Water sticks to other objects/surfaces.
What is adhesion?
When elements are attracted to each other due to opposite charges.
What is ionic bonding?
How to determine the number of neutrons in an element.
What is subtract the atomic number from the atomic mass.
These electrons determine the bonding ability of an element.
What are valence electrons?
The result of an acid combining with a base.
What is a salt and water.
Takes a lot of energy to change the temperature of water one degree.
What is high specific heat?
N + N
What is Covalent bonding?
These models are created by using the number of valence electrons.
What are Lewis Dot Diagrams?
Atoms tend to want 8 electrons in their outer energy level.
What is the octet rule?
The number of positive hydrogen ions produced is equal to the number of negative hydroxide ions produced.
What is water?
Due to polarity, water can break down solutes.
What is universal solvent?
K + F
What is an ionic bond?
The diagram that shows all of the electrons for a specific element in their appropriate shells.
What is a Bohr model?
