Investigation #3 Flashcard: Coulomb's Law, Electrons, Properties

Front

What are core electrons?

Back

Core electrons are the electrons in an atom that are not involved in chemical bonding. They are located in the inner shells of the atom.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that can participate in chemical bonding.

Front

How many valence electrons does a noble gas typically have?

Back

Noble gases typically have 8 valence electrons, except for Helium, which has 2.

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Front

Which group of elements is known as halogens?

Back

The halogens are the elements in Group 17 of the periodic table, which include Fluorine, Chlorine, Bromine, Iodine, and Astatine.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons, leading to greater stability.

Front

What are the properties of noble gases?

Back

Noble gases are colorless, odorless, and unreactive nonmetals at room temperature, with a full outer energy level.

Front

How do you determine the number of core and valence electrons in an atom?

Back

The number of core electrons can be found by subtracting the number of valence electrons from the total number of electrons in the atom.

Front

What is the electron configuration of Chlorine?

Back

The electron configuration of Chlorine is 1s² 2s² 2p⁶ 3s² 3p⁵.

Front

What is the difference between metals and nonmetals in terms of electron behavior?

Back

Metals tend to lose electrons and form positive ions, while nonmetals tend to gain electrons and form negative ions.
