What element has 45 neutrons?
Bromine
Bromine has 45 neutrons. We know this based on the fact that Bromine has an atomic number of 35 and an atomic mass of 80.
Which element has a mass number of 80?
Mercury
Mercury – Element information, properties and uses | Periodic Table.
Which isotope has 45 neutrons group of answer choices?
Bromine Br−1
So Bromine Br−1 has 35 protons, 36 electrons and 45 neutrons.
Which of the following elements is a halogen and usually has 45 neutrons in its nucleus?
It is the only liquid nonmetallic element. Bromine is a fairly heavy inorganic element. First isolated in 1826, the atomic number of bromine is 35, which means it has 35 electrons and 35 protons. Bromine also contains 45 neutrons in its nucleus, making its average atomic mass 79.9 atomic mass units.
How many protons neutrons electrons does bromine 80 have compared to bromine 83?
ANSWER: There are 35 protons, 45 neutrons, and 35 electrons in 80Br.
What is the mass number of an atom containing 35 protons and 45 neutrons answer?
80⋅amu
The mass of the nuclide is 80⋅amu .
What atom has 80 neutrons?
Summary
| Element | Mercury |
|---|---|
| Number of protons | 80 |
| Number of neutrons (typical isotopes) | 198-202 |
| Number of electrons | 80 |
| Electron configuration | [Xe] 4f14 5d10 6s2 |
How many neutrons would there be if the atomic number is 80 and the mass number is 201?
121 neutrons
The mass number (201) is the total number of protons and neutrons. So, there must be 201 – 80 = 121 neutrons. Since atoms are electrically neutral, there must be as many electrons as there are protons. A mercury atom needs 80 electrons to balance the 80 protons.
Which isotope has 45 neutrons quizlet?
A selenium (Se) atom has 45 neutrons, 34 protons, and 34 electrons.
What is the mass number of an atom containing 35 protons and 45 neutrons?
