Five proton and electrons, 6 neutrons. This because this is the atomic number of boron, which states how many protons and electron in the element. For neutrons you must subtract the atomic number (5 in this case) from the rounded. average Atomic Mass.
The atomic number of Bi is 83, so it has 83 protons and 126 neutrons.
Bismuth (Bi) has 5 valence electrons.
Bismuth (Bi) has 83 electrons, with a configuration of 2-8-18-32-18-5. There are only 5 6p electrons in bismuth.
36 + 2 + 10 + 3 = 51 electrons = 51 protons = Antimony (Sb)
In this case, the number 209 represents the sum of protons + neutrons.
Bi-211 (and all other Bi isotopes) has atom number 83, hence there are 83 protons.
The atomic number of Bi is 83, so it has 83 protons and 126 neutrons.
5 valence electrons.
5 valence electrons.
Bismuth (Bi) has 5 valence electrons.
The atomic mass doesn't equal to the number of protons. The number of protons plus the number of neutrons equal to the atomic weight... DAI BI!
Bismuth (Bi) has 83 electrons, with a configuration of 2-8-18-32-18-5. There are only 5 6p electrons in bismuth.
36 + 2 + 10 + 3 = 51 electrons = 51 protons = Antimony (Sb)
In this case, the number 209 represents the sum of protons + neutrons.
There are two unpaired electrons predicted for the ground state configuration of bismuth (Bi).
The electron configuration for Bi (Bismuth) is [Xe] 4f14 5d10 6s2 6p3. This means that Bismuth has 83 electrons in total, with the last 5 electrons occupying the 6p orbital.
The number of neutrons for the element bismuth can vary. The stable isotope is 209Bi, which has 126 neutrons.(It is actually slightly radioactive, but with a half-life of 10 million trillion years.)
