How many valence electrons would bismuth have?
Bismuth contains 5 electrons in its valence shell or its outer shell, thus it contains 5 valence electrons. As Bismuth is a Pentavalent post-transition metal thus it can be noted that it contains 5 valence electrons.
What is the valence level of an element?
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.
How is valence calculated?
valence = number of electrons in valence shell of free atom – number of non-bonding electrons on atom in molecule, valence = number of bonds + formal charge.
What level is valence electrons?
The valence electrons are the electrons in the outermost shell or last energy level of an atom. Valence electrons are electrons in the highest principal energy level. They are electrons that sit in the outermost shell of an atom. They are responsible for the chemical properties of each element.

What is the energy level of lithium?
Period 2. Explain that lithium has 3 protons and 3 electrons. There are 2 electrons on the first energy level and 1 electron on the second. Explain that the first energy level can only have 2 electrons so the next electron in lithium is on the next (second) level.
How many valence does chlorine have?
seven valence electrons
A: An atom of a group 17 element such as chlorine has seven valence electrons. It is “eager” to gain an extra electron to fill its outer energy level and gain stability.
What is the mass number of bismuth?
208.9804 uBismuth / Atomic mass
