BIOLOGY CHAPTER 3 CARDS
A solution that has a higher concentration of hydrogen ions than hydroxide ions.
the smallest, indivisible building block of matter each atom is made up of a nucleus and a electron shell.
the weight of an element determined by the addition of the protons and the neutrons.
a number assigned to every element that corresponds to the number of protons in the nucleus of the most common form of element
a one or two letter abbreviation to identify an element
a solution that has a higher concentration of hydroxide ions than hydrogen ions,
a commonly used model to describe how atoms look and interact with one another.
electrons combining together from different atoms resulting in the formation of a molecule.
equal sharing of electrons between atoms involved in a chemical bond
the falling apart of dissolving of ions in a solution
negatively charged subatomic particles that orbit the nucleus of the atom.
the area outside of the nucleus where electrons are found orbiting the nucleus.
a group of the same atoms bonded together
bonds that form between hydrogen and polar molecule in a solution containing polar chemical bonds
an atom that has a positive or a negative charge
a chemical bond that forms due to the attraction of a positive ion to a negative ion.
different forms of the same element that differ only in the number of neutrons.
the law that no mass can be lost of destroyed in a chemical reaction.
law of conservation of mass
the quantity of matter an object has.
anything that takes up space and has mass
a group of two or more atoms bonded together
a neutrally charged subatomic particle located in the nucleus of an atom.
a covalent bond resulting in the electrons being equally shared by the atoms of the bond.
the center part of the atom that contains protons and neutrons.
the property of chemical bonding that results in eight electrons filling the outer shell
the measurement of the acidity or basicity of a solution
a covalent bond resulting in electrons being slightly more attracted to one atom of the bond that the other.
the resulting molecules from a chemical reaction
a positively charged subatomic particle that is located in the nucleus of an atom
element or atoms that take place in a chemical reaction or a bond.
the molecules of a solution that are in lower quantities
a homogeneous combination of atoms in a liquid solid or gas
the molecules of a solution that are in greater quantities
particle that are smaller than an atom
What are the four classes of organic molecules?
carbohydrates proteins lipids nucleic acids
what are organic molecules?
they are molecules that living organisms make
what do all organic molecule have in common
they all have hydrogen and carbon
what do scientists think all organic molecules also have?
are organic and inorganic molecules small or large?
they are very large
which is larger organic or nonorganic molecules?
what is an isomer?
It is a molecular formula that has different forms in models, but the formula stays the same, such as a C14 H13 will be the same but in a different form.
how common is isomerization in chemistry?
what does the single line between a formula stand for?
It stands for a single covalent bond.
what does the double line between a formula?
it is a double covalent bond.
what is the three lines between a formula called
a triple covalent bond
