Group V, or group 15 as it usually called. This is bismuth
Molybdenum
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
There are 83 protons, as the atomic number of bismuth is 83.
In group 3A elements, or elements in group 13, have only one unpaired electrons.
Bismuth is an element, in the 'poor metal' group. Each Bismuth atom contains 83 Electrons, 83 Protons and 126 Neutrons

The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
Bismuth is an element with the atomic number 83 and the chemical symbol Bi.
There are 83 protons, as the atomic number of bismuth is 83.
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
Same as the group number.
group #
In group 3A elements, or elements in group 13, have only one unpaired electrons.
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
