Atomic Structure
These can exist in different amounts in atoms to form isotopes
What are neutrons?
Two or more different elements chemically combined
What is a compound?
Interactions between water molecules caused by their polar nature
What are hydrogen bonds?
The pH of these substances is low
What are acids?
What is an electron?
This indicates the number of protons in an atom
What is the atomic number?
These particles interact with other atoms during a chemical reaction
What are electrons?
Water's is high because a large amount of energy is required to change its temperature
What is heat capacity?
A single bond is formed from these
What are a pair of electrons?
This type of bond forms when atoms take or receive electrons
What is an ionic bond?
Protons and neutrons are found here
What is the nucleus?
Two atoms chemically combined form this particle
What is a molecule?
The attraction between water molecules that causes beads or droplets to form
What is cohesion?
Water's pH is this because it has equal amounts of H+ and OH- ions
What is neutral?
The building block of all matter
What is an atom?
Most of the atom's mass is located here
What is the nucleus?
Electrons are shared in this type of bond
What is a covalent bond?
The attraction of water molecules for the container or tube they are in
What is adhesion?
This type of bond results from the sharing of two pairs of electrons
What is a double bond?
Protons and neutrons are the only two particles that contribute to this quantity
What is atomic mass?
The role of protons is to do this
What is identify the atom?
The number of electrons in a neutral atom is the same as the number of these
What are protons?
Water is called this because its polar nature allows it to dissolve many different substances
What is the universal solvent?
The pH of this type of substance is high
What is a base?
This contains different types of atoms and molecules that are not chemically combined
What is a mixture?
