How many does electron protons and neutrons does selenium have?
Selenium a non metal hexagonal grey element has 34 protons and electrons. The atomic structure of Selenium has 45 neutrons.
What particles make up an atom of selenium-80?
An atom of selenium-80 contains 34 protons, 46 neutrons, and 34 electrons. Protons and neutrons are located in the nucleus of the atom, while electrons orbit around the nucleus.
How many protons and neutrons does selenium have?
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.
How many nuetrons are in selenium?
From wikipedia:"Selenium has six naturally occurring isotopes, five of which are stable: 74Se, 76Se, 77Se, 78Se, and 80Se. The last three also occur as fission products, along with 79Se which has a half-life of 295,000 years. The final naturally occurring isotope, 82Se, has a very long half-life (~1020 yr, decaying via double beta decay to 82Kr), which, for practical purposes, can be considered to be stable. Twenty-three other unstable isotopes have been characterized. " 74Se is stable with 40 neutrons 76Se is stable with 42 neutrons 77Se is stable with 43 neutrons 78Se is stable with 44 neutrons 80Se is stable with 46 neutrons see the related link for a complete table on isotopes of selenium.
What is the most common isotope for selenium?
The most common isotope of selenium is selenium-80, which makes up about 50% of naturally occurring selenium.
How many does electron protons and neutrons does selenium have?
Selenium a non metal hexagonal grey element has 34 protons and electrons. The atomic structure of Selenium has 45 neutrons.
How many nuetrons does selenium have?
Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons

How many electrons are in an atom of selenium with a mass number of 79 and an atomic number of 34?
An atom of selenium with an atomic number of 34 has 34 electrons. The mass number of 79 suggests that the total number of protons and neutrons in the nucleus is 79. Since the atomic number (protons) is given as 34, the number of neutrons can be calculated as 79 - 34 = 45.

What is the most common isotope for selenium?
The most common isotope of selenium is selenium-80, which makes up about 50% of naturally occurring selenium.
How many neutrons are in Se?
Since Selenium has an atomic number of 34, it has 34 protons and electrons at its elemental resting state. The most common isotopes have 44 and 46 neutrons, which you get from subtracting the atomic number from the atomic mass.
What are the protons in -80 selenium?
The atomic number of selenium is 34. so there are 34 protons.
How many prtons and nuetrons are in an element with an atomic number of 80?
An element with an atomic number of 80 is mercury (Hg). Mercury has 80 protons and approximately 121 neutrons in its most common isotope, mercury-201 (since 201 - 80 = 121 neutrons).
How many neutrons are in 202Hg?
There are 120 neutrons in 202Hg. Mercury-202 has an atomic number of 80, which means it has 80 protons. Neutrons can be calculated by subtracting the atomic number from the atomic mass.
How many neutrons is in caesium isotope 1?
If you think to stable isotope Ca-135 this have 80 neutrons.
