Quiz Answer Key and Fun Facts

1. Helium has an atomic number of 2 and a mass number of 4. This means that a neutral helium atom is made up of?

Answer: 2 neutrons, 2 protons and 2 electrons

The atomic number refers to the number of protons in the atom. In a neutral atom, the number of electrons equals to the number of protons.

Meanwhile, the mass number is the sum of the number of protons and the number of neutrons.

2. Choose the INCORRECT statement.

Answer: Helium is a d block element.

Helium is an s block element. Its location in the periodic table is at the 18th column (Group 18) and first row (Period 1).

3. Since helium is a noble gas, a helium atom contains 8 electrons in its outermost shell.

Answer: False

All atoms of noble gas have 8 electrons at their outermost shells, except helium. A helium atom has 2 electrons at its outermost shell.

4. There are 6 known helium isotopes. Which of these isotopes is the most abundant one? (Hint: Given that the mass number of helium is approximately 4.)

Answer: Helium-4

Only helium-3 and helium-4 are stable isotopes. The mass number for any element is the relative average of its isotopes. The mass number of an element will be close to the value of the mass number of the isotope that is the most abundant.

5. Helium can be synthesized through the bombardment of lithium or boron with?

Answer: Protons

However, this method is not used to produce helium in large scales. Production of helium gas commercially is done by using the more economical frictional distillation of natural gases.

6. Which of the following particles is identical to a helium nucleus?

Answer: An alpha particle

An alpha particle consists of 2 neutrons and 2 protons. Alpha particles are produced from the emission of radioactive nuclei, such as uranium and plutonium. They are highly ionizing particles, but have low penetration.

7. If a person has inhaled helium gas, his or her voice would sound very high-pitched. This is known as the?

Answer: Vocal effect

The speed of sound in helium is 3 times greater than the speed of sound in air. Don't try this, because excess inhalation of helium will result in asphyxiation!

8. All of the followings are uses of helium, EXCEPT?

Answer: As colorful gas in lamp tubes

Neon gas is used as inert gas to fill lamp tubes. This prevents oxidation of tungsten (wolfram) of the lamps' filaments.

Answer: Uranium and thorium

Elements with heavier mass will show radioactivity because they are unstable. Uranium and plutonium are the most common ones.

10. After hydrogen, helium is the second most abundant element in the universe.

Answer: True

Helium is also the second lightest element after hydrogen.
