What number is selenium?
The atomic number of selenium is 38 and its mass number is 78.96
What is the atomic number of selenium?
Selenium, with the chemical symbol Se, is the chemical element with the atomic number 34.
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 is the atomic number of se?
The atomic number of Selenium is 34.
How many protons and neutrons does selenium have?
The atomic number of selenium is 34. So there are 34 protons. In Se-80, there will be 46 neutrons (80 - 34 = 46) Note: There is no isotope Selenium-30 as originally asked in the question.
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.
