What is the Bohr model of the atom?

Back

The Bohr model is a theory that describes the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, similar to planets orbiting the sun.

How do you determine the number of neutrons in an atom?

Back

The number of neutrons can be found by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number).

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many electrons can the first shell of an atom hold?

Back

The first shell can hold a maximum of 2 electrons.

Front

What is the significance of the periodic table in relation to atomic structure?

Back

The periodic table organizes elements based on their atomic number and properties, helping to predict their behavior and relationships with other elements.

Front

What element is represented by the symbol 'Si'?

Back
