Ionic bonding

Front

What is ionic bonding?

Back

Ionic bonding is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other.

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

What is the charge of a sodium ion (Na+)?

Back

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

Front

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

Back

The charge of a chloride ion (Cl-) is -1.

Front

What is the formula for sodium chloride?

Back

The formula for sodium chloride is NaCl.

Front

What does the '2' in MgBr₂ represent?

Back

The '2' in MgBr₂ indicates that there are 2 bromide ions for every magnesium ion.

Front

What happens to the electrons in ionic bonding?

Back

In ionic bonding, one atom loses electrons to become a positively charged ion, while another atom gains those electrons to become a negatively charged ion.

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 significance of the 'IDE' suffix in chemical names?

Back

The 'IDE' suffix indicates that the compound contains two different elements, typically one being a nonmetal.

Front

How do you determine the charge of an ion from its position in the periodic table?

Back

The charge of an ion can often be determined by its group number in the periodic table; for example, elements in Group 1 form +1 ions, while those in Group 17 form -1 ions.
