If it has 11 electrons it must have 11 protons to balance the charge. So the element is Na. But you know it's going to be an isotope of Na since the number of protons and number of neutrons are different. To find out which isotope you have, you must get the mass number which is just the number of protons plus the number of neutrons (remember, they are the only ones that have mass) 11+12= 23
So you have Na-23
The noble gas with atoms in the ground state having the same electron configuration as nitrogen in a molecule of isocyanic acid is Neon. Both nitrogen and neon have the electron configuration of 1s² 2s² 2p³ in their ground state.
CaCl2 . electronic configuration of ca2+ 1s2 2s2 2p6 3s2 3p6. electronic configuration of Cl1- 1s2 2s2 2p6 hope this helped!
No. Lithium is an alkali metal (or group 1 element).
Answering by example: Cl- ion, Ar atom, K+ and Ca2+ ions are all 'iso-electronic' to each other, because they all have the same 20 electrons in the same (noble gas) electron configuration (structure) as argon has: [Ar] = [1s2, 2s2 2p6, 3s2 3p6]
A hydrogen nucleus has got just one electron, thereby meaning that it can either accept one more electron or give away its sole electron to attain the stable electronic configuration. However, it usually shows the non metallic behaviour of accepting an electron.
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the periodic table, we see that zinc is the element with 30 protons.
The element with the noble-gas configuration Ne 3s2 is sodium (Na). Sodium has an electron configuration of 1s2 2s2 2p6 3s1, but when it loses one electron, it attains the stable electron configuration of neon by having 2 electrons in the 3s orbital.
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
The electronic configuration of copper is [Ar] 3d10 4s1, where [Ar] represents the electron configuration of the noble gas argon. This configuration takes into account the stability gained by having a full d subshell (10 electrons) in the 3d orbital.
The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
By having a close look on the electronic configuration we can easily tell that which element will combine with the other elements and by which force too.
The electronic configuration of an atom is related to its position in the periodic table because elements in the same group have similar electronic configurations due to having the same number of valence electrons. Elements in the same period have varying electron configurations as atomic number increases across the period. This organization helps predict elements' chemical properties and behaviors.
1s22s22p3
Noble gasAn atom's atomic number tells us its number of protons and electrons. Checking the periodic table for the element having an atomic number of 18, we find that it is argon. Argon's electron configuration is 1s2 2s2 2p6 3s2 3p6, which has all of its energy levels filled.
By adding one electron to an element with 9 protons and 10 neutrons, you would create a negatively charged ion. The electron would occupy an orbital in the electron cloud, resulting in the element being one electron short of achieving a stable electron configuration. This ion would have a charge of -1 due to the extra electron.
