Atoms
These are the building blocks for all matter.
Atoms
This is concept is defined by the number of its protons.
Element
This is the most abundant element in the atmosphere
Nitrogen (N)
This concept has the same number of protons and a different number of neutrons.
Isotopes
This table contains all of the elements known today.
The Periodic Table of Elements
These three parts make up an atom.
Neutrons, Protons, Electrons
This is another name for the number of protons named on an element on the periodic table
This is the most abundant element in the human body.
Oxygen (65%)
How do you calculate the mass number?
Protons + neutrons
This is the name of the rows on the periodic table.
Periods
These two parts are contained in the nucleus.
Neutrons and protons
This is the name for the number at the bottom of the element on the periodic table, measured in atomic mass units.
Average atomic mass
This is the only metal that exists as liquid at normal temperatures
Mercury (Hg)
This version of an element has an unequal number of protons and electrons
Ions
This is the name for the first group on the periodic table
Hydrogen and alkali metals
This part of the atom constitutes most of its mass.
The nucleus
This is the name of the two letter combination seen for each element on the periodic table.
Symbol.
This is the symbol for Berkelium.
Bk
This is the name for a positively charged ion.
Cation
What is special about the eighth group?
They are noble gases and have a full valence shell.
What part of the atom has the fastest motion? (out of protons, neutrons, and electrons)
Electrons
This group on the periodic table is known for being good electrical and thermal conductors, ductile, and malleable.
Alkali metals (group 1)
This many elements were discovered at UC Berkeley.
16
This is the primary isotopes for Helium.
Helium 4
This is the first element in the third group.
Boron
