Periodic Table Bases
This tells you how many protons are in an atom
What is the atomic number?
Group 1 elements are known as these highly reactive metals?
What are alkali metals?
Negatively charged particles that are found outside the nucleus.
What are electrons?
A bond formed by sharing electrons.
What is a covalent bond?
The ability of an atom to attract electrons.
What is electronegativity?
Elements in the same column share similar properties and valence electrons.
What is a group (family)?
Group 18 elements rarely react with others.
What are noble gases?
The center of the atom contains protons and neutrons.
What is the nucleus?
A bond formed by transferring electrons.
What is an ionic bond?
Atomic size generally increases going in this direction on the table.
What is down a group?
This horizontal row of the periodic table shows energy levels.
What is a period?
These elements are found in Group 17 and are very reactive nonmetals.
What are halogens?
Particles with no charge.
What are neutrons?
This bond occurs between a metal and another metal.
What is a metallic bond?
Energy needed to remove an electron.
What is ionization energy?
Most elements on the periodic table fall into this category.
What are metals?
Elements that have properties of both metals and nonmetals.
What are metalloids?
The number of electrons in the outermost shell.
What are valence electrons?
Weak attraction between molecules, not atoms.
What are intermolecular forces?
Most reactive metals are found here on the table.
What is the bottom left?
This element has an atomic number of 8.
What is Oxygen?
The element most essential for combustion.
What is Oxygen?
This determines an atom's identity.
What is the number of protons or atomic number?
Bond where electrons are shared unequally.
What is a polar covalent bond?
The type of bond formed when sodium reacts with chlorine.
What is an ionic bond?
