The atomic number of selenium is 38 and its mass number is 78.96
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
Selenium, with the chemical symbol Se, is the chemical element with the atomic number 34.
The mass of selenium is approximately 78.96 atomic mass units. The atomic number of selenium is 34.
The atomic number of selenium is 34. so there are 34 protons.
Selenium has 6 electrons in its outermost shell.
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
Selenium, with the chemical symbol Se, is the chemical element with the atomic number 34.
The mass of selenium is approximately 78.96 atomic mass units. The atomic number of selenium is 34.
A simply formula is the atomic mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.
Number of protons in Selenium is 34.
The atomic number of selenium is 34. so there are 34 protons.
Selenium has 6 electrons in its outermost shell.
Selenium has an atomic number of 34, which means it has 34 protons. To find the number of neutrons in selenium-80, subtract the atomic number (34) from the isotope number (80). Therefore, selenium-80 would have 46 neutrons (80 - 34).
Element atomic number 34 is Selenium. Do google search for "Selenium density"
663.7 is the melting point of selenium.. and its true,, i promise ,, mmmwhhahahaah
Slenium has 34 protons and 45 neutrons! :)
Selenium is represented by the symbol Se on the periodic table. It is a nonmetal element with various industrial uses, including in electronics and glass manufacturing.
