Semester 1 Practice Assessment

Front

What are noble gases?

Back

Noble gases are a group of chemical elements that are odorless, colorless, monatomic gases with very low chemical reactivity. They include helium, neon, argon, krypton, xenon, and radon.

Front

What is the electron configuration of Neon?

Back

The electron configuration of Neon is 1s² 2s² 2p⁶.

Front

What is the charge of an atom that loses electrons?

Back

If an atom loses electrons, it becomes positively charged, forming a cation.

Front

What is the atomic structure of an oxygen atom?

Back

An oxygen atom has 8 protons, 8 electrons, and typically 8 neutrons.

Front

What is the significance of the periodic table color coding?

Back

The color coding on the periodic table helps to categorize elements based on their properties, such as metals, nonmetals, and noble gases.

Front

What does the term 'orbital notation' refer to?

Back

Orbital notation is a way of representing the arrangement of electrons in an atom's orbitals using arrows and lines.

Front

What is the atomic number of Neon?

Back

The atomic number of Neon is 10, which means it has 10 protons.

Front

What happens to the charge of an atom when it gains electrons?

Back

When an atom gains electrons, it becomes negatively charged, forming an anion.

Front

What is the electron configuration for Magnesium?

Back

The electron configuration for Magnesium is 1s² 2s² 2p⁶ 3s².

Front

What is the difference between protons and neutrons?

Back

Protons are positively charged particles found in the nucleus of an atom, while neutrons are neutral particles that also reside in the nucleus.
