Explore the fundamental building blocks of matter by constructing models, analyzing data, and solving problems related to atomic structure. This task card covers concepts such as atomic models and subatomic particles, identifying the atom, the number of electrons in the valence shell, the Bohr model, and isotopes.

Task Description:

1. Components of an Atom:

• Identify and describe the three main subatomic particles: protons, neutrons, and electrons.
• Understand the charges, masses, and locations of these particles within the atom.
• Calculate the number of protons, neutrons, and electrons of atoms and ions.
• Learn about isotopes and how they differ in terms of neutron numbers.

2. Atomic Number and Mass Number:

• Define atomic number (Z) and mass number (A).
• Calculate the number of protons, neutrons, and electrons in the atom given its atomic number and mass number.

3. Bohr model

• Draw the Bohr model of the atom.
• Identify the atom of the element and the number of valence electrons.

Be prepared to demonstrate your models, show your work, and explain atomic structure concepts. By the end of this task, students should be able to:

• Describe the structure of an atom and ion, including the properties of protons, neutrons, and electrons.
• Calculate the number of subatomic particles in an atom using atomic number and mass number.
• Describe the isotopes of elements.
• Draw the Bohr model of the atom, and identify the number of electrons in the valence shell and the number of energy levels.
