What type of compound consists of two nonmetals?
Molecular compound
True or False: Ionic compounds typically have high melting points.
True
Fill in the blank: Acids are substances that donate _____ ions in solution.
hydrogen
Which of the following is an example of a base? A) HCl B) NaOH C) CO2
B) NaOH
What is the primary characteristic of ionic compounds?
They are formed from the electrostatic attraction between oppositely charged ions.
What is an ionic bond?
An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.
True or False: Ionic bonds are formed between two nonmetals.
False: Ionic bonds are typically formed between a metal and a nonmetal.
Fill in the blank: When an ionic bond is formed, one atom ______ electrons while another atom ______ electrons.
loses; gains
Which of the following pairs of elements would most likely form an ionic bond? A) Na and Cl B) O and H C) C and N
A) Na and Cl
What happens to the energy levels of atoms when an ionic bond is formed?
The energy levels are stabilized as the oppositely charged ions attract each other, resulting in a lower energy state.
