Atomic Bohr Models

Front

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.

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 a valence electron?

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 Sodium (Na) have?

Back

Sodium has 1 valence electron.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the chemical properties and reactivity of the element.

Front

What element does the Bohr model with 11 electrons represent?

Back

The Bohr model with 11 electrons represents Sodium (Na).

Front

How many valence electrons does Chlorine (Cl) have?

Back

Chlorine has 7 valence electrons.

Front

What is the maximum number of electrons that can occupy the second shell of an atom?

Back

The second shell can hold a maximum of 8 electrons.

Front

What element would Chlorine most likely bond to and why?

Back

Chlorine would most likely bond to Hydrogen (H) because it needs one more electron to complete its outer shell.

Front

What is the atomic number of Silicon (Si)?

Back

The atomic number of Silicon (Si) is 14, which means it has 14 electrons.
