Ionic Bonding and Lattice Structures

The video tutorial explains ionic bonding, focusing on why electrons move from sodium to chlorine due to differences in electronegativity. It describes how metals and non-metals interact, forming lattice structures. The tutorial also covers naming conventions for ionic compounds, emphasizing the importance of not including charges in chemical formulas.

Why do electrons move from sodium to chlorine in ionic bonding?

• Because chlorine has fewer electrons than sodium.

• Because sodium is more electronegative than chlorine.

• Because sodium has more electrons than chlorine.

• Because chlorine is more electronegative than sodium.

What is electronegativity?

• A measure of an atom's stability.

• A measure of an atom's weight.

• A measure of an atom's desire for electrons.

• A measure of an atom's size.

Which type of elements are typically electron donors in ionic bonding?

• Non-metals

• Metals

• Metalloids

• Noble gases

What happens when multiple atoms engage in ionic bonding?

• They form a single molecule.

• They form a lattice structure.

• They remain as individual atoms.

• They form a gas.

In a lattice structure, how are ions arranged?

• In a single line

• Alternating positive and negative charges

• In pairs of two

• Randomly scattered

What is the chemical formula for sodium chloride?

• NaCl2

• Na+Cl-

• NaCl

• Na2Cl

Why don't we include charges in the chemical formula of sodium chloride?

• Because the charges cancel each other out.

• Because the charges are too small to matter.

• Because sodium and chlorine are neutral elements.

• Because it is a convention to omit them.

What is the correct name for the compound formed by sodium and chlorine?

• Sodium chloride

• Sodium plus chloride minus

• Sodium chlorite

• Sodium chlorate

What mistake should be avoided when writing the formula for sodium chloride?

• Writing the formula as NaCl2

• Using the wrong symbols for sodium and chlorine

• Including the charges in the formula

• Writing the formula as ClNa

What happens to the charges of sodium and chlorine when they form an ionic bond?

• They both become neutral.

• Sodium becomes positive, and chlorine becomes negative.

• Sodium becomes negative, and chlorine becomes positive.

• They both become positive.
