In response to a question a student stated that in an atom the number of protons is greater than the number of neutrons which in turn is greater than the number of. For example if we want to make the orbital diagram for chlorine Cl element 17 which has 17 electrons we would do it like this.
What Are The 5 Postulates Of Dalton S Atomic Theory Atomic Theory Chemistry Lessons Study Chemistry
The electrons in outer orbits do not only orbit the nucleus but they also move around the inner electrons so the effective charge Z that they feel is reduced by the number of the electrons in the inner orbit.
. Now that you have this all you need to do to find another atoms electron configuration is just fill in this pattern from the beginning until you run out of electrons. This is easier than it sounds. 1s 2 2s 2 2p.
By the time we get to fluorine F which has an effective nuclear charge of 9 2 7 and neon 10 2 8 each of the electrons are very strongly attracted to the nucleus and very difficult to dislodge. For example the lithium atom has two electrons in. Isotopes have the same atomic numbers.
Electrons that are in the same electron shell do not interact much and each electron is attracted by all the unshielded charge on the nucleus. Meaning that the size of the. Structure of the Atom Class 9 Extra Questions Short Answer Type 1.
No they do not because the two elements differ in their atomic numbers.
