Subatomic Particles
This particle has a negative charge.
What is an electron?
This is the very center of an atom.
What is an atomic nucleus?
This is the number of protons within an atom. It defines elements and represents the place of an element on the periodic table.
What is the atomic number?
This decreases as we move right along the periodic table.
What is the reactivity of elements?
This groups is the most unstable group and possesses only one valence electron.
What are the Alkali metals?
This particle has a positive charge.
This is the formula for which the total number of electrons in an energy level can be calculated.
What is 2n2?
This is the weighted average of the mass of particles contained within the nucleus of a particular element.
What is the atomic mass?
This increases from right to left and downward.
What is the atomic radius?
This group consists of Fluorine, Chlorine, bromine, Iodine, and astatine.
What are the Halogens?
This particle has no charge.
What is a neutron?
This is the outer most electron orbital.
What is a valence shell?
This is the count of neutrons and protons within the nucleus of an atom and is found by rounding the atomic mass.
What is the atomic mass number?
From left to right and from bottom to top this increases.
What is electronegativity?
This group is the first representative group to possess all three types of elements within one group.
What is the Carbon Family?
These two particles have identical masses.
What are protons and neutrons?
This is a charged atom.
What is an ion?
Each A group within the periodic table contains elements that have this in common.
What are similar properties? OR what is the number of outer valence electrons?
This increases as you go downward in a representative group and is obvious starting in the Carbon family.
What is metallicity? (or any other phrasing of it gets more metallic as it goes downward)
These groups contains Metals, Metalloids, and non-Metals as well as solids and gasses.
What are the nitrogen and oxygen families?
This particle has such a small mass it can be ignored.
What is an electron?
This is an atom with a non-standard number of neutrons in the nucleus.
What is an isotope?
Metals, Metalloids, and non-metals.
What are three types of elements on the periodic table?
What is the atomic mass?
This group contains highly reactive, soft, metals.
What are the Alkali Earth Metals?
