Ionic bonding Flashcards
What atoms bond with each other which shell is involved usually?
The outermost electron shell or valence shell
why do atoms combine with each other?
to achieve a more stable electronic configuration
What happens when atoms bond?
A chemical change takes place
What are the three different types of bonding?
Ionic, covalent, metallic
What does ionic bonding occur between?
Metals and non-metals
What happens in ionic bonding?
valence electrons are transferred from metal atom/s to non-metal atom/s
what do metal atoms form?
Positive ions known as cations
What do non-metal ions form?
Negative ions known as anions
ionic bonding forms what?
ionic compounds
what are ionic compounds held together by?
A strong force of attraction known as electrostatic forces of attraction
Know how to illustrate ionic bonding
please
What is an ion?
a particle with positive or negative charge an ion forms when particles gain or lose electrons from the valence shells
What do metal ions do?
Metal ions from groups (1,2,3) lose electrons to positively charged ions called cat ions
What do non-metal ions do?
Non-metal ions from groups (,5,6,7) gain electrons from metal ions and are negatively charged
Unlike atoms, in an ion…
The number of protons and electrons are NOT equal
