Analyze periodic table matching

We match statements 1–8 with items a–j:

• Statement 1: "vertical column in the periodic table" matches group (i).
• Statement 2: "A repetition of properties occurs when elements are arranged in order of increasing atomic number" matches periodic law (f).
• Statement 3: "type of element that is a good conductor of heat and electric current" matches metal (d).
• Statement 4: "type of element characterized by the presence of electrons in the d orbital" matches transition metal (e).
• Statement 5: "basis for Mendeleev's arrangement of the periodic table" matches atomic mass (g).
• Statement 6: "subatomic particles that are transferred to form positive and negative ions" matches electrons (j).
• Statement 7: "ability of an atom to attract electrons when the atom is in a compound" matches electronegativity (a).
• Statement 8: "energy required to remove an electron from an atom" matches ionization energy (b).

Analyze chemical bonding matching

We match statements 9–12 with items a–f:

• Statement 9: "a depiction of the arrangement of atoms in molecules and polyatomic ions" matches structural formula (c).
• Statement 10: "a covalent bond in which only one pair of electrons is shared" matches single covalent bond (d).
• Statement 11: "a covalent bond between two atoms of significantly different electronegativities" matches polar bond (e).
• Statement 12: "a type of bond that is very important in determining the properties of water and of important biological molecules such as proteins and DNA" matches hydrogen bond (f).

Analyze chemical kinetics matching

We match statements 13–15 with items a–e:

• Statement 13: "the minimum energy colliding particles must have in order to react" matches activation energy (d).
• Statement 14: "the number of atoms, ions, or molecules that react in a given time to form products" matches reaction rate (b).
• Statement 15: "a substance that interferes with a catalyst" matches inhibitor (c).
