Who does the worst Yoda impression?

Complete the following definition of the first ionisation energy: The energy required to [blank_start]remove[blank_end] one [blank_start]electron[blank_end] from each atom in [blank_start]one mole[blank_end] of [blank_start]gaseous atoms[blank_end] to form [blank_start]one mole[blank_end] of [blank_start]gaseous 1+ ions[blank_end].

How many p-orbitals make up one p-subshell?

Complete the following definition of relative atomic mass: The average [blank_start]weighted[blank_end] mass of an atom of an [blank_start]element[blank_end] relative to [blank_start]1/12[blank_end] of the mass of a [blank_start]carbon-12[blank_end] atom.

The first ionisation energy of boron is higher than the first ionisation energy of beryllium.

Complete the following processes that occur during mass spectrometry in the correct order: Vaporisation [blank_start]Ionisation[blank_end] [blank_start]Acceleration[blank_end] [blank_start]Deflection[blank_end] [blank_start]Detection[blank_end] Recording

Fill in the blanks: To 2 decimal places, Avogadro's constant is [blank_start]6.02[blank_end] × [blank_start]10^23[blank_end].

Fill in the blanks: The y-axis of a mass spectrum is the percentage abundance of an isotope. The x-axis is mass/[blank_start]charge[blank_end] ratio.

What is room temperature and pressure?

What are "standard conditions"?

Fill in the blanks to complete the Ideal Gas Equation: p[blank_start]V[blank_end] = [blank_start]n[blank_end]R[blank_start]T[blank_end]

In the Ideal Gas Equation, what is volume measured in?

A C-Cl bond is polar.

Fill in the blank: The strength of London forces is primarily determined by the number of [blank_start]electrons[blank_end].

Fill in the blank: The bond angle of the Cl-P-Cl bond in PCl_3 is [blank_start]107[blank_end] degrees.

What is the oxidation number of sulfur in Na₂S₄O₆?

Sort the period 3 non-metals (silicon, phosphorus, sulfur, chlorine, argon) in order of increasing boiling points: [blank_start]Argon[blank_end], [blank_start]chlorine[blank_end], [blank_start]phosphorus[blank_end], [blank_start]sulfur[blank_end], [blank_start]silicon[blank_end]

What colour flame do strontium ions make when burned?

A homogeneous catalyst is used in the contact process.

Hydrogen bonding only occurs when which atoms are bonded to hydrogen? Write them below in order of decreasing strength of the hydrogen bond (FULL words, not symbols): [blank_start]Fluorine[blank_end], [blank_start]oxygen[blank_end], [blank_start]nitrogen[blank_end]
