The octet rule is a simple chemical rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electronic configuration as a noble gas.
For me this means that the "Octet Rule" is just a chemical rule that explains the atoms and the electronic configuration.

What is a Bohr Diagram?
The Bohr model, devised by Niels Bohr, depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus—similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity.
What I am trying to say is that the nucleus orbits around the solar system but with electrostatic force.

What is a Lewis Dot Diagram?
The Bohr model gives almost exact results only for a system where two charged points orbit each other at speeds much less than that of light. This not only includes one-electron systems such as the hydrogen atom, singly-ionized helium, doubly ionized lithium, but it includes positronium and Rydberg states of any atom where one electron is far away from everything else.
In my own words this would mean that a Bohr model gives a similar result only for a system where two charged points each other at speeds which are not that fast such as light; and that it shouldn't always include one-electron system such as the hydrogen atom, singly-ionized helium, doubly ionized lithium, but it includes positronium and Rydberg states of any atom where one electron is far away from everything else.

What element is this? How can you decide? Post a comment to my post below and tell me what you think it is?
It is Argon, because there are 18 electrons in the picture, and that's the atomic mass number of Argon.
ReplyDeleteIt is the element Argon because there are 18 electrons and the atomic mass of Argon is 18. This is the count of electrons.

ReplyDeleteI believe this is Argon, because on the periodic chart, the atomic number represents the numbers of protons. This image has 18 electrons, and the 18th atomic number is Argon.
ReplyDeleteI believe that this element is Argon because there are 18 electrons and the atomic number is 18. This means that there are 18 protons and 18 neutrons in the nucleus of the atom. Argon was discovered in 1894 by Lord Rayleigh and Sir William Ramsay, England. It makes up 1% of the atmosphere. It is obtained from liquefying air.
ReplyDeleteI strongly believe that the element in the picture is Argon. I believe this because Argon has 3 shells, 2 electrons on the 1st, 8 on the second,and 8 on the 3rd shell, just like the picture above.
ReplyDeleteI am pretty sure this element is Agron because it consists of 18 electrons. The name used in the periodic table of elements is Ar, which has been used since 1957. Argon is a colorless and odourless gas present to a very small extent in the atmosphere.
