List the items you should bring into the lab for non-practical lessons.

• Notebook and pen

• Lab coat and goggles

• Calculator and ruler

• Textbook and highlighter

True or False: You can bring food and drink into the lab.

• True

• False

What should you do if there is a spill in the lab?

• Clean it up immediately without any protective gear.

• Inform the teacher and follow the safety protocols.

• Ignore it and continue working.

• Leave the lab immediately without informing anyone.

All matter is composed of:

• Atoms

• Cells

• Molecules

• Compounds

The basic structure of the atom can be shown by:

• a diagram of the nucleus and electron cloud

• a chemical equation

• a periodic table

• a molecular formula

What are the attributes of sub-atomic particles?

• Mass, charge, and spin

• Color, taste, and smell

• Size, shape, and texture

• Temperature, pressure, and volume

The atomic structure of an atom determines its place in the periodic table based on:

• The number of protons in the nucleus

• The number of neutrons in the nucleus

• The number of electrons in the outer shell

• The atomic mass of the atom

The 'atomic number', 'mass number', and 'neutron number' of elements are:

• atomic number is the number of protons, mass number is the sum of protons and neutrons, neutron number is the difference between mass number and atomic number

• atomic number is the sum of protons and neutrons, mass number is the number of protons, neutron number is the difference between mass number and atomic number

• atomic number is the number of neutrons, mass number is the sum of protons and neutrons, neutron number is the number of protons

• atomic number is the number of electrons, mass number is the sum of electrons and neutrons, neutron number is the difference between mass number and atomic number

Electronic shells are filled in a specific order. How does this order relate to their position on the periodic table?

• They are filled randomly, unrelated to the periodic table.

• They are filled in order of increasing energy levels, which corresponds to their position on the periodic table.

• They are filled in order of decreasing energy levels, which corresponds to their position on the periodic table.

• They are filled based on atomic mass, unrelated to the periodic table.

Isotopes are atoms of the same element with different numbers of what?

• Protons

• Neutrons

• Electrons

• Nuclei
