What is the percentage of iron in the earth crust?
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
Is argon a rare or common element?
Argon is a common element in the Earth's atmosphere, making up about 0.93% of the air we breathe. While it is not as abundant as nitrogen or oxygen, it is considered a common element in terms of its presence on Earth.
What is the ratio of helium?
The ratio of helium in the universe is approximately 24% by mass, primarily produced during the Big Bang nucleosynthesis. In terms of abundance in the solar system, helium constitutes about 10% of the Sun's mass and is the second most abundant element after hydrogen. In Earth's atmosphere, helium is found in trace amounts, making up only about 0.0005% of the atmosphere.

What is the abundance of potassium?
Potassium is the 7th most abundant element in Earth's crust, making up about 2.1% of its mass. In living organisms, potassium is the most abundant cation found inside cells and plays a vital role in various physiological processes. In terms of relative abundance in the universe, potassium is not as common as elements like hydrogen, helium, and oxygen.
Is 74 an abundant number?
No, 74 is not abundant in mathematical terms.
Most abundant element in the body?

Interstellar dust consists mostly of?
Hydrogen with some helium. However, trance amounts of other materials are seldom found in the interstellar regions of space like water, ammonia, methane, etc. And we are talking in terms of parts per trillion if not more.
Is carbon scarce or abundant?
Carbon is abundant on Earth, as it is found in various forms like graphite, diamond, and in the atmosphere as carbon dioxide. However, in terms of the carbon cycle and environmental sustainability, there is concern about the increasing levels of carbon dioxide in the atmosphere due to human activities, leading to climate change.

What is the the most abundant element by weight in human body?
Oxygen.Oxygen is the most abundant element in the earth's crust and in the body. The body's 43 kilograms of oxygen is found mostly as a component of water, which makes up 70% of total body weight. Oxygen is also an integral component of all proteins, nucleic acids (DNA and RNA), carbohydrates, and fats.Well, this amount of oxygen obviously might vary according to the weight of every individual, age, gender, etc. However, in terms of percentage, oxygen keeps on being the most abundant element.
