CHEM 103 EXAM 1 IU QUESTIONS
AND ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT!!!
Q: What is the term for the vertical columns (up and down) on the periodic
table? A: ✔️✔️ Group (or Family)
Q: What is the term for the horizontal rows (left to right) on the periodic
table? A: ✔️✔️ Period
Q: What does the Atomic Number represent? A: ✔️✔️ It indicates the total
number of protons found in the nucleus of an atom.
Q: How is the Mass Number calculated? A: ✔️✔️ By finding the sum of both
protons and neutrons within the atom.
Q: What logic is used to organize the periodic table? A: ✔️✔️ It is structured
based on increasing atomic mass and the similarity of chemical properties and
reactivity.
Q: What information can be gathered from an element's Group? A: ✔️✔️
Elements in the same group share similar chemical reactivity and bonding
characteristics.
Q: What trend is observed moving across a Period? A: ✔️✔️ There is a
consistent increase in atomic mass as you move from left to right.
, Q: What are the defining physical traits of Metals? A: ✔️✔️ They are
typically solid at room temperature, malleable (can be hammered flat), ductile
(can be drawn into wire), and excellent conductors of heat and electricity.
Q: What are the general characteristics of Nonmetals? A: ✔️✔️ They can
exist as liquids or gases at room temperature and are generally poor conductors
(with few exceptions like carbon in graphite form).
G1 -ANSWER ✔️✔️Alkali metals, soft, react w water to create alkaline
G2 -ANSWER ✔️✔️alkaline earth metals, very reactive but not as violent w
water as alkali
g7 -ANSWER ✔️✔️halogens
g8 -ANSWER ✔️✔️noble gases
intensive properties -ANSWER ✔️✔️don't rely on sample size; temperature,
melting point
extensive property -ANSWER ✔️✔️rely on sample size; length, volume
physical property -ANSWER ✔️✔️no change in the actual element; temperature,
color, odor, solubility
chemical property -ANSWER ✔️✔️change in chemical make up; rusting,
combustion, tarnishing, cooking/burning
