The Chemistry Hot Seat
• Break into groups.
• I will provide you with a question.
• Everybody in the group will write down
the question and provide an answer for
the question.
• One person is on the Hot Seat, I will
check their answer first.
Scoring
Scoring is as follows…
• If the person on the Hot Seat answers the
question correctly, your team will score 6 points.
• If the person on the Hot Seat answers it
incorrectly, I will check the remainder of the
groups answers. You will score a single point for
every correct answer provided.
Note: Group members are not allowed to share
their answers.
Question #1
What are the 3 components that make
up an atom?
You must have all three to be correct.
1. Electrons (negative)
2. Protons (positive)
3. Neutrons (no charge)
Question #2
This component of an atom possesses
relatively no mass?

Question #12
What is an ion? How is it formed?
An ion is an atom with a charge.
It is formed when an atom gains or loses
an electron.

Alkali Metals
Question #15
What family forms -1 ions?
Halogens
Question #16
It has been considered a family of one,
and can carry properties of both
metals and non-metals…
Hydrogen
Question #17
A chemical formula tells us 3 things,
what are they?
The type of elements in a compund, the
number of each atom present, and the
type of compound (ionic or covalent)
formed.
Question #18
How many atoms are in the following
compound? 4Al2(CO3)3
Ensure to segment the compound and count the
number of atoms of each element.
Aluminum (Al) 8
Carbon (C)
12
Oxygen (O)
36
Total
56
Question #19
What type of elements make up an ionic
compound?
Non-metal + Metal
Question #20
In an ionic comound, what type of
elements lose electrons and which
type gains electrons?
Metals lose electrons and are therefore
positively charged (Cations).
Non-metals gain electrons and are
therefore negatively charged (Anions).
