Periodic Table Trends
This is what happens to the first ionisation energy as you move across the periodic table
What is increase?
The number of moles are in 2.0 g of hydrogen gas (H₂)
What is 1 mol?
The most likely category for a substance that has a low melting point and does not conduct electricity
What is simple covalent?
This sublevel can hold a maximum of 2 electrons
What is the s-orbitals?
This is the number of sides a dodecahedron has.
What is 12?
This element has the highest electronegativity out of all the elements on the periodic table
What is fluorine?
This formula is used to calculate the number of moles from mass.
What is n = m / M?
The physical property that describes an ease to shatter rather than bend out of shape
What is brittle?
How many orbitals make up a d sublevel?
What is 5?
This is the chemical symbol of Silver
What is Ag?
This atomic property decreases down a group due to increased electron shell levels.
What is the atomic/ionic radius?
The number of molecules in 0.5 mol of CO₂
What is 3.01 × 10²³ molecules?
This is the name of the structure used to describe the ionic, metallic and covalent network.
What is a lattice?
This element has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁵
What is Chlorine?
The capital city of Canada
What is Ottawa?
This property increases as you move across a period from left to right due to increasing nuclear charge.
What is electronegativity?
In the reaction 2H₂ + O₂ → 2H₂O, if you have 4 mol H₂ and 1 mol O₂, this is the limiting reactant.
What is oxygen (O₂)?
The reason for why metallic substances can conduct electricity
What is 'the sea of electrons'?
Which element has an outer electron configuration ending in 3p³
What is Phosphorus?
This is what www stands for in the url of websites.
What is World Wide Web?
These are the 2 reason why electronegativity changes, which also thereby causes polar bonds
What is:
Different distance from the central positive nucleus
More protons in the central nucleus for electrons in the same shell/orbital
A student reacts 10.0 g of CaCO₃ with 100.0 mL of 1.50 M HCl according to the equation:
CaCO₃(s)+2HCl(aq)→CaCl₂(aq)+CO₂(g)+H₂O(l)
This is the mass of CO₂ produced
What is 3.30 grams?
This is the physical property you would test should you already know a substance has a high melting point to determine whether it is ionic or metallic
What is testing for conductivity of electricity as a solid?
The electron configuration of sodium (Z = 11)?
What is 1s² 2s² 2p⁶ 3s¹?
This is the most abundant gas in Earth's Atmosphere
What is Nitrogen?
