What is mass number of arsenic?
Arsenic is a non metallic element. Mass number of it is 75.
About 75 by mass of Earth's crust is composed of what two elements?
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%.
What is arsenics mass number?
Arsenic is a non metal element. Atomic mass of it is 75.
What element has an atomic mass greater than 75 but less than 79?
Element 34, Selenium, has an atomic mass of about 78.96.
What element makes up most of the detectable mass in the universe?
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.
What is the mass number of As-3?
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.
If 75 percent of the isotopes of an element have a mass of 35.0 amu and 25 percent of the isotopes have a mass of 37.0amu what is the atomic mass of the element?
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.
What is the most abundant formed of element?
The most abundant element in the universe is hydrogen.
What element makes up about 75 percent of the sun's mass?
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.
