Group 1 – The Alkali Metals
• Watch the demo.• Write down your observations.• Write down the chemical reactions (word and
symbol)

Group 1 and 7 elements react with each other.
• Can you explain why?

In an IONIC bond,electrons are lost or gained,resulting in the formation of IONS
in ionic compounds.

In covalent bonding,atoms still want to achievea noble gas configuration.

In covalent bonding,atoms still want to achievea noble gas configuration.
But rather than losing or gainingelectrons,atoms now share an electron pair.

In covalent bonding,atoms still want to achievea noble gas configuration.
But rather than losing or gainingelectrons,atoms now share an electron pair.
The shared electron pairis called a bonding pair
