How many electrons are allowed per Orbital?

s-orbitals can hold 2 electrons, the p-orbitals can hold 6 electrons. Thus, the second shell can have 8 electrons. The n=3 (third) shell has: The 3s orbital.
A.

How many electrons are in the 4th Shell?

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
B.

What is the shell number for the outer shell electrons in bromine?

Bromine is a member of the halogen family of elements. Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals.
  • How many electrons are in the outer shell of helium?

    It was observed that the atoms of elements,having a completely filled outermost shell show little chemical activity. In other words their combining capacity is 0. Of these inert elements, the helium atom has 2 electrons in its outermost shell and all other elements have atoms with 8 electrons in the outermost shell.
  • Where bromine can be found?

    Bromine is found naturally in the earth's crust and in seawater in various chemical forms. Bromine can also be found as an alternative to chlorine in swimming pools. Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire).
  • How do you determine the number of electrons in an atom?

    You can simply subtract the atomic number from the mass number in order to find the number of neutrons. If the atom is neutral, the number of electrons will be equal to the number of protons. 1. Your mass number is the total number of neutrons and protons within the atom.
C.

How many electrons are in the outer shell of oxygen?

Oxygen is #8 in the periodical table. First electron shell can hold 2 electrons; second, 8. Therefore, out of 8 electrons, 2 go to the first shell and 6 to the second; valence electrons are the ones on the outermost shell (there are some exceptions, but they are much further down the table).
  • How many electrons are in the outer shell of sulfur?

    So for the element of SULFUR, you already know that the atomic number tells you the number of electrons. That means there are 16 electrons in a sulfur atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and six in shell three.
  • How many electrons will each gain or lose in forming an ion?

    Calcium-loses 2, Fluorine-gains 1, Aluminum-loses 3, Oxygen-gains 2.
    How many electrons will each of these elements gain or lose in forming an ion: calcium, fluorine, aluminum, and oxygen? +1.
    Identify the charge of the ion formed when a potassium atom loses one electron.
  • What is the number of electrons to fill the outer shell of carbon?

    Explanation: The octet rule states that atoms can fill their outer shells with up to 8 electrons (a full shell of 8 is the most stable configuration). Since Carbon only has 4 of its outer electron slots (or valence electrons) full, it has room to make bonds with 4 other atoms, assuming they are all single bonds.
