• Neon

• Phosphorus

• Oxygen

• Manganese

Which one answer of the following is CORRECT?

• Metals can be solid, liquid, or gas

• Non-metals are shiny and brittle

• Metals are good conductors of electricity and can be hammered into thin sheets

• Non-metals are insulators and lustrous

Which one answer of the following is CORRECT?

• The number of protons equals the number of neutrons

• The atomic mass number is equivalent to the number of protons in an atom.

• Isotopes are atoms of the same element with different numbers of neutrons

• The mass of an neutron is 2000 times smaller than the mass of an electron

Which one option of the following is CORRECT?

• Zirconium (Zr) is in group five and, therefore, has four electron shells

• Selenium is in period six and, therefore, has six valence electrons

• Iodine is in group seven and, therefore, has seven valence electrons

• Neon is in group two and, therefore, has two electron shells

Which one option of the following is CORRECT?

• Elements in the same period have similar chemical properties

• Elements in the same group have the same valence electrons

• Elements in group eight are called the halogens

• Elements in period one react violently with water

Which of the following options is CORRECT?

• The atomic radius decreases when going up a group

• The atomic radius increases when going left to right across a period

• The atomic radius of Fluorine is larger than that of Boron

• The atomic radius of Aluminum is larger than that of Calcium

Which of the following options is CORRECT?

• The electrons in hydrogen chloride are pulled more towards the hydrogen atom

• The electronegativities of the elements decrease when going up a group

• The electrons in gaseous Bromine are shared equally

• When an atom has a greater number of protons, it becomes less electronegative

Which of the following options is CORRECT?

• The alkaline earth metals are generally more reactive than the alkali earth metals

• The halogens are unreactive and stable because of their complete electron octet

• The alkaline earth metals are light and reactive, but not as reactive as the alkali metals

• The noble gases are the most reactive non-metals
