== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Is atomic mass unit a SI unit of an atomic mass?
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
What is the mass and atomic number of selenium?
Selenium is a non metal element. Atomic number of it is 34.
Which atom has the atomic mass of 79?
Selenium
What number is selenium?
The atomic number of selenium is 38 and its mass number is 78.96
How many electrons are in an atom of selenium with a mass number of 79 and an atomic number of 34?
Selenium with an atomic mass of 80 has 46 neutrons.
How many neutrons are in selenium-76?
A simply formula is the atomic mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.
What element has an average atomic mass nearest to 79?
Selenium
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 has the mass number of 78?
THE ELEMENT WHICH HAVE ATOMIC MASS 78.96 IS SELENIUM OF 6TH GROUP WITH ATOMIC NUMBER 34 AND SYMBOL (Se)
What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
What element is represented by the symbol Se?
Selenium, atomic number 34.
How many grams in one mole of silicon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Selenium's atomic mass is 78.96 grams.
What is the atomic number of selenium?
Selenium, with the chemical symbol Se, is the chemical element with the atomic number 34.
