What is a substance called in which atoms of two or more elements are chemically combined?
A compound
An atom
A lattice
What bonding is it when electrons are shared?
Covalent
Ionic
Bonding involves the highest energy level of an atom
Atoms don't want to achieve a full outer shell like a noble gas
If atoms lose electrons they form...
Negatively charged ions
Positively charged ions
If atoms gain electrons...
What do group 1 metals react with to form ionic compounds, with a metal ion that has a single positive charge?
Non-metals
metals
What do group 7 element react with to form ionic compounds, in which halide ions have a single negative charge?
Alkali metals
Metals
What is an ionic compound?
a giant structure of ions
A small structure of ions
Ions with a single charge
Why are ionic compounds held together by strong electrostatic forces?
The ions are oppositely charged
The ions have the same charge
The structure is large
The forces acting in all directions is called ionic bonding
Covalent bonding forms a __________ bond betwen atoms
Weak
Strong
In metal atoms the electrons in the outer shell become delocalised so are free to move about the structure
