Periodic Table
This periodic trend increases as you move down a group.
What is atomic radius?
These elements are found in Group 1 of the periodic table.
What are alkali metals?
This subatomic particle carries a negative charge.
What is an electron?
This type of bonding forms between metals and nonmetals.
What is ionic bonding?
This type of bonding occurs between nonmetals.
What is covalent bonding?
This property increases as you move left to right across a period.
What is electronegativity?
What are noble gases?
This part of the atom contains most of its mass.
What is the nucleus?
This describes what happens to electrons during ionic bonding.
What is electron transfer?
This describes how electrons behave in a covalent bond.
What is electron sharing?
Among sodium, magnesium, and aluminum, this element has the largest atomic radius.
What is sodium (Na)?
This is the typical ionic charge formed by alkaline earth metals.
What is +2?
This is the number of valence electrons in an oxygen atom.
What is six?
This ion is formed when sodium loses one electron.
What is Na+?
This type of covalent bond involves unequal sharing of electrons.
What is a polar covalent bond?
This explains why the atomic radius decreases across a period due to increased nuclear charge.
What is the stronger attraction between the nucleus and electrons?
These elements contain seven valence electrons.
What are halogens?
This atomic property tells you the number of protons in an atom.
What is the atomic number?
This explains why ionic compounds have high melting points.
What is a strong electrostatic attraction between ions?
This explains why water is a polar molecule.
What is unequal electronegativity and a bent molecular shape?
This element has the highest electronegativity on the periodic table.
What is fluorine?
This explains why transition metals are good conductors of electricity.
What are delocalized (free-moving) electrons?
This is the charge of an atom with 17 protons and 18 electrons.
What is -1?
What is MgCl2?
This bond is more polar between C-H and O-H.
What is O-H?
