Basic Concepts of Chemical Bonding

This set of flashcards covers key concepts related to chemical bonding, including Lewis symbols, lattice energy, ionic charges, compound formation, bond lengths, bond polarity, and formal charges.

What is the Lewis Symbol for Calcium (Ca)?

The Lewis Symbol for Ca is represented by its element symbol 'Ca' with two dots indicating two outer electrons.

What is the Lewis Symbol for Magnesium ion (Mg2+)?

The Lewis Symbol for Mg2+ shows 'Mg' with no dots, indicating it has lost its two outer electrons.

Which compound has the highest lattice energy among KF, NaF, CsI, CaO?

CaO has the highest lattice energy due to the higher charge of Ca2+ and O2- compared to the other ions.

What is the typical charge for Strontium (Sr) when ionic?

The typical charge for Strontium (Sr) is +2.

What is the typical charge for Sulfur (S) when ionic?

The typical charge for Sulfur (S) is -2.

What is the typical charge for Aluminum (Al) when ionic?

The typical charge for Aluminum (Al) is +3.

What compound will form between cesium and chlorine?

Cesium chloride (CsCl) will form between cesium (Cs) and chlorine (Cl).

What compound will form between aluminum and oxygen?

Aluminum oxide (Al2O3) will form between aluminum (Al) and oxygen (O).

What is the Lewis dot structure for water (H₂O)?

The Lewis dot structure for H₂O has two hydrogen atoms bonded to oxygen with two lone pairs on the oxygen.

In bond lengths, which is longer: N-N, N=N, or N#N?

N-N has the longest bond length compared to N=N and N#N.

Which bond is more polar: B-Cl or C-Cl?

C-Cl is more polar than B-Cl due to the greater electronegativity difference between C and Cl.

What are the formal charges on S and each O in SO2?

The formal charges on S and each O in SO2 are 0, 0, 0.

What are the formal charges on S and each O in SO3?

The formal charges on S and each O in SO3 are +1, -1, -1, -1.
