Topic 1-3 IB Chemistry SL

Front

Which oxides produce an acidic solution when added to water?

Back

Acidic oxides include SiO2, P4O6, and SO2. Specifically, P4O6 and SO2 produce acidic solutions.

Front

What is the electron arrangement of silicon?

Back

Silicon has an electron arrangement of 2.8.4.

Front

Which compound has the empirical formula with the greatest mass?

Back

C4H10 has the greatest empirical formula mass among C2H6, C4H10, C5H10, and C6H6.

Front

What is the emission spectrum of the hydrogen atom?

Back

The emission spectrum shows lines that converge at lower energies, produced when electrons move from higher to lower energy levels.

Front

Order the atomic radius of Na, K, and Mg from smallest to largest.

Back

The correct order is Mg, Na, K.

Front

Define acidic oxides.

Back

Acidic oxides are oxides that react with water to form acids.

Front

What is the significance of the electron arrangement in elements?

Back

The electron arrangement determines an element's chemical properties and reactivity.

Front

What is an empirical formula?

Back

An empirical formula represents the simplest whole-number ratio of atoms in a compound.

Front

Explain the concept of atomic radius.

Back

Atomic radius is the distance from the nucleus to the outermost electron shell.

Front

What is the relationship between energy levels and emission spectra?

Back

Electrons emit energy in the form of light when they transition from higher to lower energy levels.
