It depends which diagram, most likely they are electron shells as all elements have
No, Earth does not have any rings around it. Saturn, Jupiter, Uranus, and Neptune are the planets in our solar system that have rings. Earth is not one of them.
Potassium fluoride is a polar compound due to the difference in electronegativity between potassium and fluorine atoms, resulting in an uneven distribution of electrons. This creates a slight negative charge around the fluoride ion and a slight positive charge around the potassium ion, making the molecule polar.
It looks like thisK–Br:except that there are also two dots both above and below the "Br" in the diagram (there are three lone pairs on Br, and none on K)See the Related Questions link about Lewis Dot Structures to the left of this answer for more help with electron dot diagrams!
The rock and ice particles that create a circle around a planet are called rings. These rings are composed of various-sized particles that orbit around the planet. Saturn is the most well-known planet with a prominent ring system.
Potassium has an atomic number of 19 and a mass number close to 39. To draw an atom of potassium, its important to know the following:Atomic number = number of protons = number of electronsMass number = number of protons + number of neutronsFrom this, we can work out the number of protons, neutrons and electrons in potassium:Protons in potassium = 19Electrons in potassium = 19Neutrons in potassium = 20Now, the protons and neutrons are located in the center of an atom called the nucleus so you would need to draw 19 protons and 20 neutrons at the center of the atom. Surrounding the nucleus are electrons that are located in sub-atomic shells. The electrons exist in an order that is called the electronic configuration. For the first 20 elements, the electronic configuration is 2, 8, 8, 2. You would therefore need to draw 4 "rings" around the nucleus. These rings will act as your sub-atomic shells. In the first ring, you would draw 2 electrons, followed by 8 electrons in the second and third ring, and finally 1 electron in the fourth ring.
A dot diagram, or Lewis dot structure, illustrates the valence electrons of an atom. Calcium (Ca) has two valence electrons, represented by two dots, while potassium (K) has one valence electron, represented by a single dot. Therefore, the dot diagram for calcium would show two dots around the symbol, while potassium would show one dot.
. k it looks like that above
No it does not have rings around it
like to rings that are connected.
4 - the configuration is 2-8-8-1.
All inner planets does not have rings around it.
The rings around planets are called planetary rings. They are made up of countless small particles, ranging in size from micrometers to meters, that orbit around the planet due to gravitational forces.
no mercury does not have rings
No it does not have rings around it
yes,there are 11 rings around Uranus.
yes it has about 360000 thousand rings rotating around it
There are no rings around the earth so they do nothing.
