Intro to Chemistry
An element represented by the symbol "H."
What is Hydrogen?
This subatomic particle is found in a "cloud" surrounding the nucleus and has a negative charge.
What is an electron?
The term that describes an area of scientific knowledge used to describe the arrangement of electrons about an atom's nucleus.
What is quantum mechanics?
Columns of elements on the periodic table.
What are families or groups?
This family of elements has a full valence shell and therefore does not ionize.
What is the noble gas family?
A substance that cannot be separated into simpler substances through chemistry
What are elements?
Meaning "indivisible" or unable to divide again.
What are atoms?
The first quantum number; the quantum number that describes the the different energy levels surrounding the nucleus of an atom.
What is the principle quantum number?
Family of elements found on the far right side of the periodic table. These elements are stable of non-reactive.
What is the noble gas family?
The ionized form of fluorine.
What is fluoride?
The study of matter and how various kinds of matter react with each other.
What is Chemistry?
These subatomic particles are found in the nucleus of the atom.
What are protons and neutrons?
The quantum number that states the p-shaped orbits may be aligned along three imaginary axes: x, y, and z.
What is the magnetic quantum number?
The energy required to remove electrons.
What is ionization energy?
The element magnesium gains/loses ______ electrons as it ionizes.
loses
2
Any substance, whether it be solid, liquid, or gas.
What is matter?
The theory that states that all elements are made of atoms.
What is the atomic theory?
Tells the shape of the path in which the electrons are traveling.
What is the orbital quantum number?
Energy required to add electrons to atoms.
What is electron affinity?
The ion symbol for Astatide.
What is At-1?
The medieval forerunner of chemistry, based on the supposed transformation of matter. It was concerned particularly with attempts to convert base metals into gold or to find a universal elixir.
What is alchemy?
The amount of matter found in an object.
What is mass?
This atom has 12 electrons in its electron cloud, with two in the spherical shaped s-orbit on the first energy level, two electrons in the s-orbit on the second energy level, a total of six electrons divided among the three p-orbits, and two electrons in the s-orbit at the third energy level.
What is magnesium?
The most reactive elements know to man.
What is the sodium family?
The ion symbol for Radium Ion.
What is Ra+2?
