Bohr Rutherford diagrams

Front

What is the atomic number of an atom?

Back

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

Front

What is a valence electron?

Back

Valence electrons are the electrons located in the outermost energy level of an atom, which are involved in chemical bonding.

Front

How many valence electrons does an atom with atomic number 6 have?

Back

An atom with atomic number 6 (Carbon) has 4 valence electrons.

Front

Which element has 6 valence electrons?

Back

The element with 6 valence electrons is Oxygen (atomic number 8).

Front

What is a metalloid?

Back

Metalloids are elements that have properties of both metals and nonmetals, and they are typically found along the zig-zag line on the periodic table.

Front

What is the significance of the Bohr model?

Back

The Bohr model describes the structure of an atom with electrons orbiting the nucleus in defined energy levels.

Front

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

Back

The number of protons in an atom is equal to the atomic number of the element.

Front

What is the relationship between atomic number and element identity?

Back

The atomic number uniquely identifies an element; no two elements have the same atomic number.

Front

What are the main components of a Bohr Rutherford diagram?

Back

A Bohr Rutherford diagram includes the nucleus (protons and neutrons) and the electron shells (energy levels) surrounding it.

Front

How many electrons can the first energy level hold?

Back

The first energy level can hold a maximum of 2 electrons.
