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 is the atomic mass of the element Ne?
Neon is a non meta element. Atomic mass of it is 20.
What does the atomic mass of an element measure?
Atomic mass of an element measures the mass of that element on a molecular scale, taking into account neutrons and protons, which weigh approximately 1. Electrons are negated. Atomic mass is also the mass, in grams, of 1 mole of that element.
What element that has an atomic mass of 14.007?
Nitrogen, element 7, has an atomic mass of 14.0067, rounded to 14.007.
Which element has an atomic mass of 200?
Mercury has an atomic mass of 200.
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 is the mass number of AS?
Asenic is a non metal element. Atomic mass of it is 75.
What is arsenics mass number?
Arsenic is a non metal element. Atomic mass of it is 75.
What element composed 75 of mass?
Arsenic has an atomic weight of 74,921 595.
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.
How do you find the number of proton and atomic number in the mass number 75?
You have to know the element with the mass number of 75. Then you would look it up on the periodic table to find the atomic number, which is the number of protons.
What is mass number of arsenic?
The mass number of arsenic is 75, as it is the sum of the number of protons and neutrons in the nucleus of an arsenic atom.
What is the atomic mass for magnesiam?
The atomic mass of magnesium is approximately 24.305 amu (atomic mass units).
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
Which element has the atomic mass of 126.9045?
The element is Iodine (I). It has an atomic mass of about 126.9.
Atomic number 75?
The atomic number of 75 corresponds to the element rhenium (Re) on the periodic table. Rhenium is a dense, silvery-white metal that is used in high-temperature superalloys and catalysts due to its high melting point and stability.
Which element has an atomic mass of 16.00?
the element that has an atomic mass of 16.00 is sulfer.
