Front

What is a Lewis dot diagram?

Back

A Lewis dot diagram is a representation of the valence electrons of an atom, depicted as dots around the chemical symbol of the element.

Front

How do you draw a Lewis dot diagram for Magnesium?

Back

For Magnesium (Mg), place two dots around the symbol (Mg) to represent its two valence electrons.

Front

What does the nucleus of an atom contain?

Back

The nucleus of an atom contains protons and neutrons.

Front

What are protons?

Back

Protons are positively charged particles found in the nucleus of an atom.

Front

What are neutrons?

Back

Neutrons are neutral particles found in the nucleus of an atom.

Front

What is a valence electron?

Back

A valence electron is an electron located in the outermost shell of an atom.

Front

How many valence electrons does Iodine have?

Back

Iodine has 7 valence electrons.

Front

How many electrons can fit on the 1st energy level (orbital) for any Bohr Model?

Back

The 1st energy level can hold a maximum of 2 electrons.

Front

What is the maximum number of electrons in the 2nd energy level?

Back

The 2nd energy level can hold a maximum of 8 electrons.

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.
