Bohr Models & Lewis Structures

Front

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 valence electrons does Lithium have?

Back

Lithium has 1 valence electron.

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.

Front

What is the atomic number of Helium?

Back

The atomic number of Helium is 2.

Front

What are noble gases?

Back

Noble gases are elements in Group 18 of the periodic table that are characterized by having a full outermost electron shell, making them very stable and unreactive.

How many valence electrons does Iodine have?

Back

Iodine has 7 valence electrons.

Front

What is a Bohr model?

Back

A Bohr model is a diagram that represents an atom with a central nucleus surrounded by electrons in defined orbits.

Front

What element is represented by a Bohr model with 3 electrons?

Back

The element represented is Lithium.

Front

What is the significance of the outermost electron shell?

Back

The outermost electron shell determines an atom's chemical properties and its ability to bond with other atoms.

Front

What is the electron configuration of Carbon?

Back
