This isotope is shown in hyphen notation: on the left side of the hyphen is the isotope's name, and on the right side is the isotope's mass number. The mass number of an element is the total number of particles in the nucleus (the number of protons + neutrons an atom has).
In order to get the number of protons an atom has, find its atomic number on the Periodic Table. Selenium's atomic number is 34.... wait, this doesn't make any sense. If it has a mass number of 30 and an atomic number of 34, it has -4 neutrons.
I'm sorry, but it looks like you have the problem wrong.
What else can I help you with?
How many does electron protons and neutrons does selenium have?
Selenium has 34 electrons, 34 protons, and different isotopes of selenium can have varying numbers of neutrons. The most common isotope of selenium, selenium-80, has 46 neutrons.
What has 34 protons and 45 neutrons?
Selenium-79 is a radioisotope of selenium containing 34 protons and 45 neutrons.
How many protons neutrons and electrons are in a selenium atom?
Selenium (Se) has an atomic number of 34 which means in a balance atom Se will have 34 protons and 34 electrons then Se has a mass of 79 so to get the neutrons we minus the protons from the mass and we get 45 final answer: Neutrons: 45 Protons:34 Electrons: 34
What is the mass number of a selenium atom that has 31 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Since selenium usually has 34 neutrons, an atom of selenium with 31 neutrons would have a mass number of 34 (31 neutrons + 17 protons).
How many neutrons are found in -80 selenium?
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).
How many does electron protons and neutrons does selenium have?
Selenium has 34 electrons, 34 protons, and different isotopes of selenium can have varying numbers of neutrons. The most common isotope of selenium, selenium-80, has 46 neutrons.

How many neutrons are found in -80 selenium?
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).
