depending on the number of electrons an element has determines the number of arrows in the orbitals. there is always one going up and one going down if the energy level is filled. Remember hund's rule in that each level must contain one arrow before another gets two. and the bottom figures are 1s^1 2s^2 3px 3py 3pz 4d.... and so forth
The orbital notation for beryllium (Be) is 1s^2 2s^2. This notation represents the distribution of electrons in the beryllium atom's electron shells and subshells.
Electronic configuration of boron: [He]2s2.2p1.
The electron configuration of thorium is: [Rn]6d27s2.
The orbital notation for beryllium (Be) is 1s^2 2s^2, representing the distribution of its 4 electrons into the first and second energy levels, with 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.
The noble gas notation for Y (yttrium) is [Kr] 4d1 5s2. This notation indicates that yttrium has the electron configuration of krypton plus two electrons in the 5s orbital and one electron in the 4d orbital.
The orbital notation for thallium is [Xe}4f14.5d10.6s2.6p1.
dont include it
An unoccupied orbital is represented by an empty box in orbital notation. It does not have any electrons present in it but is available to accept electrons if needed.
The orbital notation for vanadium is 1s2 2s2 2p6 3s2 3p6 4s2 3d3.
The element with this orbital notation is nickel (Ni), a transition metal.
In scientific notation all numbers are written in the form: a*10b where a is a decimal number such that 1 ≤ a < 10 and b is an integer.
The orbital notation for oxygen is 1s^2 2s^2 2p^4. This indicates that oxygen has two electrons in the 1s orbital, two electrons in the 2s orbital, and four electrons in the 2p orbital.
[Rn]7s2
The orbital notation for beryllium (Be) is 1s^2 2s^2. This notation represents the distribution of electrons in the beryllium atom's electron shells and subshells.
Electronic configuration of boron: [He]2s2.2p1.
I don't know what you mean "how to write the rules." In the US, "standard" notation means "long form", i.e. 6,000,000, while "scientific" notation means the exponential form, 6x106. I had thought it was the same in the UK, but Mehtamatics says otherwise: "Standard notation and scientific notation are the same in terms of UK usage of these phrases."
The electron configuration notation for oxygen is 1s2 2s2 2p4. This indicates that oxygen has 8 electrons, with 2 in the 1s orbital, 2 in the 2s orbital, and 4 in the 2p orbital.
