Exploring Atomic Structure and Trends

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

What is the charge of a chloride ion (Cl^-)?

Back

The charge of a chloride ion (Cl^-) is -1, indicating it has gained one electron.

Front

What is the significance of valence electrons?

Back

Valence electrons determine an element's chemical properties and its ability to bond with other elements.

Front

How do elements in the same group of the periodic table behave chemically?

Back

Elements in the same group have similar chemical properties because they have the same number of valence electrons.

Front

What is the charge of a sodium ion (Na^+) after losing one electron?

Back

The charge of a sodium ion (Na^+) is +1.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.

Front

What is the role of protons in an atom?

Back

Protons determine the atomic number of an element and its identity; they are positively charged particles found in the nucleus.

Front

What is the atomic number of chlorine?

Back

The atomic number of chlorine is 17, which means it has 17 protons.
