• Neutrons are electrically neutral.

• Electrons are positively-charged.

• Electrons are negatively-charged.

Multiple Select

Select the particle(s) that are found in the nucleus of the atom.

• protons

• neutrons

• electrons

Multiple Choice

Is the following statement true or false?

The mass of an atom is largely determined by the number of protons and neutrons.

• True

View the next video on isotopes before you apply what you learnt to answer some questions.

​This is Periodic Table Notation.

​

​C is the symbol for Carbon.

​The '6' is the Atomic Number of Carbon. This means Carbon has 6 protons in its nucleus.

​The '6' is the Atomic Number of Carbon. This means Carbon has 6 protons in its nucleus.
