10 Questions
What is the octet rule in chemistry?
It states that atoms lose, gain, or share electrons to attain the electronic configuration ns2np6 of the nearest noble gas.
Why are noble gases generally unreactive?
Due to their high ionization energies and low electron affinity.
What is the key role of the valence electrons in chemical bonding?
To participate in covalent bonds.
Why do atoms combine to form compounds?
To achieve a stable electron configuration by sharing, losing, or gaining electrons.
What characteristic makes main-group monoatomic ions similar to noble gases?
They have a filled outer level of electrons, similar to noble gases.
What is the main purpose of atoms combining to form compounds?
To decrease potential energy
In an ionic bond, what type of elements typically participate?
An electropositive element and an electronegative element
What happens when an atom loses electrons in an ionic bond?
It becomes a cation
Which type of bond results from the sharing of valence electrons?
Covalent bond
Why do most atoms form chemical bonds with each other?
To create more stable arrangements by decreasing potential energy
