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
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 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 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 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 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 are the number of protonsneutrons and electrons in selenium?
protons=5 neutrons=10 electrons = 34
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 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.
How many protons neutrons and electrons does selenium-55 have?
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
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 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).
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
What is selenium's mass number?
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
What element has 34 electrons?
The element with 34 electrons is selenium. Selenium has an atomic number of 34, which indicates the number of protons and electrons in a neutral atom of selenium. It is a nonmetal with chemical symbol Se and is commonly used in various industrial applications, including electronics and glass manufacturing.
