The element with the electron configuration 1s2 2s2 2p6 3s2 3p6 is Argon, which has an atomic number of 18.
that is fluorin
This group has the electron configuration of sulfur. The element sulfur has 16 electrons, and its electron configuration is 1s2 2s2 2p6 3s2 3p4.
The most electronegative element is fluorine. Its electron configuration is 1s2 2s2 2p5.
The element is argon
Lithium (Li) has the electron configuration 1s2 2s1.
The element with this electron configuration is arsenic (As), with 33 electrons.
Iron is a 'd' block element with electronic config. 1s2 2s2 2p6 3s2 3p6 4s2 3d6. Iron tends to loose the outermost 4s2 electrons to form Fe2+ and later form Fe3+ quickly to attain 3d5 config. as per rule, a half filled d orbital will be more stable i.e. Fe3+. hence iron gets oxidised to Fe3+ easily. Example is the formation of rust. But, zinc is not considered purely a d block element. it has a 3d10 config. which gives inertness
The element with the electron configuration 1s2 2s2 2p6 is neon (Ne).
This element is chlorine (group 17).
Helium.
Noble gas config: [Ne] 3s2, 3p5Electron config: 1s2, 2s2, 2p6, 3s2, 3p5
only one proton means only one electron, therefore, electron config is 1 or 1s1 when acting as a non-metal in an ionic sustance H- has an electron config of 2 or 1s2
The element that corresponds to the electron configuration 1s2 2s2 is Beryllium (symbol Be), which has an atomic number of 4. It has 4 electrons, with 2 in the 1s orbital and 2 in the 2s orbital.
The element with the electron configuration 1s2 2s2 2p6 3s2 3p6 is Argon, which has an atomic number of 18.
5 electrons: 1s2 2s2 2p1, so an uncharged atom would have 5 protons: Boron.
The electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d7 represents the element manganese (Mn), which has an atomic number of 25.
