Term 2 Revision Quiz- Year 9

The three subatomic particles in the atom are:

• Proton, Neutron, Electron

• Proton, Photon, Neutrino

• Electron, Positron, Neutron

• Neutron, Muon, Proton

The protons and neutrons sit in the center of the atom, which is called the:

• nucleus

• electron cloud

• valence shell

• orbital

The 'mass number' of an atom is:

• the total number of protons and neutrons in the nucleus

• the number of electrons in the atom

• the atomic number of the atom

• the number of protons in the nucleus

Fill in the table below with the location and charge of the three subatomic particles.

• Proton | Nucleus | +1 Neutron | Nucleus | 0 Electron | Electron cloud/orbitals | -1

• Proton | Electron cloud/orbitals | +1 Neutron | Nucleus | -1 Electron | Nucleus | 0

• Proton | Nucleus | 0 Neutron | Electron cloud/orbitals | +1 Electron | Nucleus | -1

• Proton | Nucleus | -1 Neutron | Electron cloud/orbitals | 0 Electron | Nucleus | +1

For the following elements in atomic notation, name the element and then calculate the number of protons, neutrons and electrons present. Atomic Notation | Element | Electrons | Protons | Neutrons 19/9 F | | | | 36/17 Cl | | | | 23/11 Na | | | |

An isotope is defined as which of the following?

• Atoms of the same element with different numbers of neutrons

• Atoms of different elements with the same number of protons

• Atoms of the same element with different numbers of protons

• Atoms of different elements with the same number of neutrons

The general equation for when an acid and metal react is:

• Acid + Metal → Salt + Hydrogen gas

• Acid + Metal → Water + Salt

• Acid + Metal → Metal oxide + Hydrogen gas

• Acid + Metal → Salt + Oxygen gas

Select the general equation for a neutralization reaction and provide an example.

• Acid + Base → Salt + Water; e.g., HCl + NaOH → NaCl + H₂O

• Acid + Metal → Salt + Hydrogen; e.g., HCl + Zn → ZnCl₂ + H₂

• Base + Metal → Salt + Water; e.g., NaOH + Zn → Na₂ZnO₂ + H₂O

• Acid + Carbonate → Salt + Water + Carbon Dioxide; e.g., HCl + Na₂CO₃ → NaCl + H₂O + CO₂

The general reaction for when an acid reacts with a carbonate is:

• Acid + Carbonate → Salt + Water + Carbon Dioxide

• Acid + Carbonate → Salt + Hydrogen Gas

• Acid + Carbonate → Salt + Oxygen + Water

• Acid + Carbonate → Salt + Carbon Monoxide
