Introduction to Chemistry: Atomic structure, Safety and SOM

In her chemistry class, Mia is on a mission to uncover the secrets of a carbon atom. Can you help her figure out how many protons, neutrons, and electrons this mysterious atom contains?

Answer explanation

A carbon atom has 6 protons, 6 neutrons, and 6 electrons. The number of protons defines the element as carbon, and in a neutral atom, the number of electrons equals the number of protons.

What atom is shown in the diagram?

Hint which subatomic particle determine the element?

Answer explanation

The atom shown in the diagram is determined by its number of protons, which defines the element. If the diagram indicates 6 protons, it represents Carbon, as Carbon is the element with atomic number 6.

In a lively science class, Aiden and Kai are on a quest to uncover the mysteries of electricity. They stumble upon a curious question: Which subatomic particle carries a negative charge? Can you assist them in their electrifying adventure?

• Protons

• Neutrons

• Electrons

Answer explanation

The subatomic particle with a negative charge is the electron. Protons have a positive charge, while neutrons are neutral, meaning they have no charge.

In a lively science class, Abigail was curious to know which subatomic particle, residing in the nucleus, is the neutral one with no charge?

• Protons

• Neutrons

• Electrons

Answer explanation

Neutrons are subatomic particles found in the nucleus of an atom and have no electric charge. In contrast, protons have a positive charge, and electrons have a negative charge.

Identify the atom in the picture.

Hint: What subatomic particle determine the element?

Answer explanation

The element is determined by the number of protons in its nucleus, which is the atomic number. Boron has 5 protons, making it the correct choice. The hint emphasizes the importance of protons in identifying the element.

What is the atomic mass of the atom in the picture?

Hint: what two particles make up the mass?

Answer explanation

The atomic mass of an atom is primarily determined by the number of protons and neutrons, which are the two particles that contribute to mass. If the atom in the picture has no protons or neutrons, its atomic mass is 0.

In a lively science class, Sophia was challenged to identify which subatomic particle is known for its positive charge. What should she shout out?

• neutron

• proton

• electron

Answer explanation

A proton is the subatomic particle that carries a positive charge. Neutrons are neutral, and electrons carry a negative charge. Therefore, Ava should answer 'proton'.

In a lively science class, Benjamin and Arjun were debating which subatomic particle is the neutral one. Can you help them figure it out?

• proton

• neutron

• electron

Answer explanation

The neutron is the subatomic particle that carries no charge, making it neutral. In contrast, protons carry a positive charge and electrons carry a negative charge.

In her science class, Sophia and her friends Anika and Michael are on a quest to uncover the mysteries of atoms. They stumble upon the concept of isotopes. Can you help them figure out what an isotope is?

• The same atom only with a different number of neutrons

• The same atom only with a different number of electrons

• The same atom only with a different number of protons

• The same atom only with a different number of neutrons and protons

Answer explanation

An isotope is defined as the same element with a different number of neutrons. This means the atomic number (protons) remains the same, but the mass number changes due to the variation in neutrons.

Join Abigail and her friends Zoe and Benjamin on a cosmic adventure as they explore the mysteries of a carbon atom! Can you help them discover how many protons, neutrons, and electrons this tiny atom holds?

Answer explanation

A carbon atom has 6 protons, 6 neutrons, and 6 electrons. The number of protons defines the element as carbon, and in a neutral atom, the number of electrons equals the number of protons.
