Which of the following is not a isotope of hydrogen?
- A.
Deuterium
- B.
Tritium
- C.
Protium
- D.
Sulphur
Correct Answer
D. SulpHurExplanation
Sulphur is not a isotope of hydrogen. Isotopes of hydrogen include deuterium and tritium, which have different numbers of neutrons compared to the most common isotope of hydrogen, protium. However, sulphur is a completely different element and is not related to hydrogen in terms of isotopes.Rate this question:

What is the molecular formula of Hydrogen?
- A.
H2
- B.
G2
- C.
O2
- D.
C4
Correct Answer
A. H2Explanation
The molecular formula of Hydrogen is H2. This is because Hydrogen is a diatomic molecule, meaning it naturally occurs as a pair of atoms bonded together. Therefore, the correct molecular formula for Hydrogen is H2, indicating that there are two Hydrogen atoms bonded together in a molecule.Rate this question:

What is the atomic number of hydrogen?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
A. 1Explanation
The atomic number of an element represents the number of protons in the nucleus of its atom. Hydrogen has an atomic number of 1, which means it has one proton in its nucleus. This is the smallest atomic number possible, as hydrogen is the simplest and lightest element on the periodic table.Rate this question:

Hydrogen combines with oxygen to form?
- A.
Water
- B.
Chlorine
- C.
Carbon Monoxide
- D.
Ozone
Correct Answer
A. WaterExplanation
Hydrogen combines with oxygen to form water. This is a well-known chemical reaction in which two hydrogen molecules (H2) react with one oxygen molecule (O2) to produce two water molecules (H2O). This reaction is essential for sustaining life on Earth, as water is a vital component for all living organisms. Additionally, water is a universal solvent and plays a crucial role in various chemical and biological processes.Rate this question:

What is the color of hydrogen?
- A.
Blue
- B.
Green
- C.
Yellow
- D.
No color
Correct Answer
D. No colorExplanation
Hydrogen is a colorless gas, and therefore it does not have a specific color. This is because it consists of only one type of atom, which does not have any inherent color. The perception of color occurs when light interacts with objects and is absorbed or reflected, but hydrogen does not interact with light in a way that produces a visible color. Thus, the correct answer is "No color".Rate this question:

What proportion of the universe's total mass is dihydrogen?
- A.
50%
- B.
60%
- C.
70%
- D.
45%
Correct Answer
C. 70%Explanation
The correct answer is 70%. This suggests that dihydrogen, also known as molecular hydrogen or H2, makes up 70% of the total mass of the universe. This is based on scientific understanding and calculations of the composition of the universe, which includes various elements and compounds. Dihydrogen is a simple molecule consisting of two hydrogen atoms bonded together, and it is believed to be abundant in the universe, particularly in interstellar clouds and gas giants like Jupiter.Rate this question:

Among the following, which has the highest relative atomic mass?
- A.
tritium
- B.
Protium
- C.
Deuterium
- D.
All have equal mass
Correct Answer
A. tritiumExplanation
Tritium has the highest relative atomic mass among the given options. Tritium is an isotope of hydrogen, with one proton and two neutrons in its nucleus. Protium is the most common isotope of hydrogen, with only one proton and no neutrons. Deuterium is another isotope of hydrogen, with one proton and one neutron. Since tritium has two neutrons, it has a higher mass than both protium and deuterium, making it the isotope with the highest relative atomic mass among the options given.Rate this question:

Another name of Deuterium is
- A.
Light hydrogen
- B.
Complex hydrogen
- C.
Heavy hydrogen
- D.
Liquid Hydrogen
Correct Answer
A. Light hydrogenExplanation
Deuterium is commonly referred to as "heavy hydrogen." This is because it is an isotope of hydrogen that has a higher mass due to the presence of an additional neutron in its nucleus. The term "light hydrogen" is used to distinguish regular hydrogen (which consists of a single proton) from deuterium. "Complex hydrogen" and "liquid hydrogen" are not accurate names for deuterium and do not reflect its isotopic composition or physical state.Rate this question:

The half life of atomic hydrogen is?
- A.
0.33s
- B.
1.33s
- C.
2.33s
- D.
6.33s
Correct Answer
A. 0.33sExplanation
The half-life of atomic hydrogen is 0.33s, which means that it takes 0.33s for half of the atoms in a sample of atomic hydrogen to decay. This indicates that atomic hydrogen is an unstable element and undergoes radioactive decay at a relatively fast rate.Rate this question:

High electric discharge causes the combination of hydrogen and oxygen to form
- A.
Hydrogen dioxide
- B.
Carbon monoxide
- C.
Hydrogen peroxide
- D.
Hydrogen sulphate
Correct Answer
C. Hydrogen peroxideExplanation
High electric discharge can cause the combination of hydrogen and oxygen to form hydrogen peroxide. This is because the energy from the electric discharge breaks the bonds between hydrogen and oxygen atoms in water molecules (H2O), resulting in the formation of hydrogen peroxide (H2O2). Hydrogen peroxide is a compound that consists of two hydrogen atoms and two oxygen atoms bonded together.Rate this question:
