Exploring Atomic Structure

What are the three main parts of an atom?

• Protons, Neutrons, Electrons

• Protons, Neutrons, Positrons

• Protons, Photons, Neutrons

• Electrons, Neutrons, Quarks

What charge do protons have?

• Positive charge

• Neutral charge

• Variable charge

• Negative charge

Where are neutrons located in an atom?

• Floating freely in the nucleus

• In the outer shell of the atom

• In the nucleus of an atom.

• In the electron cloud

How many protons does a hydrogen atom have?

• 0

• 2

• 1

• 5

What is the role of electrons in an atom?

• Electrons are only involved in nuclear reactions.

• Electrons are responsible for the chemical properties of an atom and its ability to form bonds with other atoms.

• Electrons determine the mass of an atom.

• Electrons are the heaviest particles in an atom.

What is the maximum number of electrons in the first shell?

• 2

• 8

• 1

• 10

How do you determine the atomic number of an element?

• The atomic number is the total number of electrons in an atom.

• The atomic number is the sum of neutrons and protons in an atom.

• The atomic number is the number of isotopes of an element.

• The atomic number is the number of protons in an atom.

What is the difference between an element and a compound?

• A compound is a pure substance, while an element is a mixture of different substances.

• An element consists of one type of atom, while a compound consists of two or more different types of atoms chemically bonded.

• Elements can be broken down into simpler substances, whereas compounds cannot.

• An element can be made of multiple types of atoms, while a compound is made of a single type of atom.

What is the atomic mass of an element?

• The atomic mass is the mass of an atom without considering isotopes.

• The atomic mass is the total number of protons in an atom.

• The atomic mass of an element is the weighted average of the masses of its isotopes.

• The atomic mass is the mass of the nucleus only.

What does the atomic symbol 'O' represent?

• Osmium

• Oganesson

• Oxygen

• Ozone
