Ionic and Covalent Bonding Practice

Front

In an ionic bond, what does the metal do with its electrons?

Back

The metal loses electrons.

Front

How many valence electrons does beryllium lose when forming an ionic bond?

Back

Beryllium loses 2 valence electrons.

Front

Which two elements are most likely to form a covalent bond?

Back

Phosphorus (P) and Fluorine (F).

Front

What is the charge of a non-metal when it gains an electron?

Back

It becomes a negative ion.

Front

What type of bond is formed when electrons are shared between two non-metals?

Back

Covalent bond.

Front

What type of bond is formed when one atom transfers electrons to another atom?

Back

Ionic bond.

Front

What is the general trend for electronegativity in the periodic table?

Back

Electronegativity increases from left to right across a period and decreases down a group.

Front

What is the result of an ionic bond between sodium and chlorine?

Back

Sodium loses an electron to become Na+, and chlorine gains an electron to become Cl-, forming NaCl.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is a polar covalent bond?

Back

A bond where electrons are shared unequally between two atoms, resulting in partial charges.
