Three types of bonding
covalent, ionic and metallic
100
Name the three giant structures.
Giant covalent, giant metallic, giant ionic
100
What is special about noble gas elements?
They have complete outermost shell.
100
Which particles in an atom are positively charged?
protons
100
What particles form the nucleus of an atom?
Protons and neutrons
200
Definition of ionic bond
Electrostatic force between two oppositely charge ions
200
Physical properties that giant structures have in common
High melting and boiling points
200
Elements in the same group have similar chemical properties because
The number of valance electrons is the same.
200
What determines the volume of an atom
The volume is determined by the radius of the outermost electrons. (number of shells)
200
Give 3 properties of electrons.
Negatively charged; negligible mass; orbit around the nucleus; occupy most of the space in the atom
300
True or false- All molecules contain covalent bond
True
300
Conductor of electricity has
Either free moving ions or free moving electrons
300
Which group is Halogen?
The VII group
300
What are isotopes?
Atoms of the same element with the same proton number but different neutron number.
300
What effect does a partly filled outer shell have on an atom?
The atom is likely to be unstable. It will tend to lose or gain electrons to achieve a full outer shell.
