What is represented by #1 on the periodic table INB template?

Multiple Choice

Which statement about periods on the periodic table is correct?

• Periods are columns numbered from 1-18.

• Periods are rows numbered from 1-7.

• Elements in the same period have similar chemical properties.

• Atomic number decreases from left to right.

Fill in the Blanks

The electrons in the outermost energy level of an atom are called

.

Multiple Choice

What do all elements in the same group (column) of the periodic table have in common?

• They have the same number of valence electrons.

• They have the same atomic mass.

• They have the same number of protons.

• They have the same number of neutrons.

Multiple Choice

What is the main factor that determines the reactivity of an atom?

• The number of protons in the nucleus

• The number of neutrons in the nucleus

• The number of valence electrons

• The atomic mass

Multiple Select

Which of the following statements about stable atoms are correct?

• They have a full outer energy level of electrons.

• They are usually found in Group 8A of the periodic table.

• They are highly reactive with other atoms.

• Helium is an exception as it is stable with only two valence electrons.

Fill in the Blanks

Atoms are considered stable when their outermost shell is filled with

electrons.

Multiple Choice

Why does hydrogen bond with itself to become stable?

• It needs to lose electrons to become stable.

• It needs to gain one electron to fill its outer shell.

• It needs to share electrons so both atoms have two electrons in their outer shell.

• It needs to have eight electrons in its outer shell.

Multiple Choice

Why is the water molecule (H2O) sometimes called the 'Mickey Mouse Molecule'?

• Because its structure resembles Mickey Mouse's head and ears

• Because it is found in Disneyland

• Because it is a cartoon molecule

• Because it is unstable

Multiple Choice

What did Dmitri Mendeleev do to help organize the elements, and why was his approach significant for the development of the periodic table?

• He arranged elements by atomic number, which revealed repeating patterns in properties.

• He grouped elements by color, which made the table visually appealing.

• He organized elements alphabetically, making them easier to find.

• He listed elements by their melting points, which helped in industrial applications.
