Periodic Table, Ionic and Covalent Bonds Fall 2020

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually between non-metal atoms.

Front

What are the characteristics of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved in water or molten.

Front

What are the characteristics of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points, may not be soluble in water, and do not conduct electricity.

Front

What is the significance of the periodic table in chemistry?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, helping predict element behavior.

Front

What is a group in the periodic table?

Back

A group is a vertical column in the periodic table where elements have similar chemical and physical properties due to having the same number of valence electrons.

Front

What is a period in the periodic table?

Back

A period is a horizontal row in the periodic table, indicating the number of electron shells an atom has.

Front

Which elements are most likely to form an ionic bond?

Back

Elements from Group 1 (alkali metals) and Group 17 (halogens) are most likely to form ionic bonds.

Front

What is the difference between NaF and O2 bonds?

Back

NaF is an ionic bond formed between sodium and fluorine, while O2 is a covalent bond formed by the sharing of electrons between two oxygen atoms.

What type of bond is formed between potassium (K) and bromine (Br)?

Back

An ionic bond is formed between potassium (K) and bromine (Br).
