Arsenic (As)
Yes, Atomic mass of 75 in the periodic table!
Arsenic is a non metallic element. Mass number of it is 75.
The two elements that make up about 75% of Earth's crust by mass are oxygen and silicon. Oxygen is the most abundant element, making up about 46% of the Earth's crust, while silicon is the second most abundant element, comprising roughly 28%.
Arsenic is a non metal element. Atomic mass of it is 75.
Element 34, Selenium, has an atomic mass of about 78.96.
Hydrogen is the element that makes up most of the detectable mass in the universe. About 75% of the normal matter in the universe is hydrogen.
The mass number of an element is the sum of the number of protons and neutrons in its nucleus. Arsenic typically has a mass number of around 75, so As-3 would likely have a mass number of 72 since the isotope notation includes the mass number.
The atomic mass is calculated by averaging the masses of the isotopes based on their abundance. In this case, 75% of the isotopes have a mass of 35.0 amu and 25% have a mass of 37.0 amu. Atomic mass = (0.75 * 35.0 amu) + (0.25 * 37.0 amu) = 35.5 amu.
The most abundant element in the universe is hydrogen.
Hydrogen makes up about 75% of the sun's mass. It is the primary fuel source for the sun's nuclear fusion reactions that produce energy.
