Question 11

Inorganic chem.

Answer 11

the branch of chemistry that deals with inorganic compounds.

Question 12

Organic chem.

Answer 12

noun

the chemistry of carbon compounds (other than simple salts such as carbonates, oxides, and carbides).

Question 13

Bio chem

Answer 13

noun

the branch of science concerned with the chemical and physicochemical processes that occur within living things

Question 14

Atoms

Answer 14

the basic unit of a chemical element.

Question 15

Neutron

Answer 15

noun
a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

Question 16

Proton

Answer 16

noun
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.

Question 17

Electron

Answer 17

noun
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

Question 18

Nucleus

Answer 18

the central and most important part of an object, movement, or group, forming the basis for its activity and growth.

Question 19

Elements

Answer 19

2.
each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter.

Question 20

Isotopes

Answer 20

noun
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

Question 21

Mass numbers

Answer 21

Noun

the total number of protons and neutrons in a nucleus.

Question 22

Atomic mass

Answer 22

noun
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

Question 23

Atomic number

Answer 23

Noun
the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.

Question 24

Periodic table

Answer 24

noun a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.

Question 25

Scientific notation

Answer 25

a method of writing or displaying numbers in terms of a decimal number between 1 and 10, multiplied by a power of 10.

Question 26

Quantum mechanics

Answer 26

noun the branch of mechanics that deals with the mathematical description of the motion and interaction of subatomic particles, incorporating the concepts of quantization of energy, wave-particle duality, the uncertainty principle, and the correspondence principle.

Question 27

Hunds rules

Answer 27

every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

Question 28

Orbital

Answer 28

noun each of the actual or potential patterns of electron density that may be formed in an atom or molecule by one or more electrons, and that can be represented as a wave function.
