What is the electron configuration of tc?
Technicium (Tc) can be found in period 5 group VII of the periodic table. It is a transition metal and so is a d-block element. Thus the electron configuration is [Kr]4d5 5s2
What element is an alkaline earth metal whose electron configuration ends in 6s2?
All alkaline earth metals have electron configurations ending in s2; 6s2 would be the alkaline earth metal in period 6 of the PTE, which is barium.
How is iron classified on the periodic table?
iron is a metalyeah
What element has 2 electrons in its outer shell and 12 in total?
Magnesium. The complete electron configuration is: 1s2 2s2 2p6 3s2 The complete electron arrangement is: 2e, 8e, 2e
How can emission spectrocopy be used to identify metal salts?
Each spectra is unique to each element as fingerprints are to humans because they each have their own spectral pattern and by comparing the spectra of a known element to the unknown element or ion you can identify them.
Why the metal is very reactive?
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.
What is the electron configuration of atomic number 10?
Neon is a non metal element. Atomic number of it is 10.
Write the expected ground-state electron configuration for the alkaline earth metal after radium?
You think probably at Unbinilium (120Ubn) an element not still obtained. The supposed electron configuration of Ubn will be [Uuo]7s2.
Is chromium a noble gas?
The electron configuration of the ion Cr(III)+ is 1s22s22p63s23p63d3
What is the electron configuration of tc?
Technicium (Tc) can be found in period 5 group VII of the periodic table. It is a transition metal and so is a d-block element. Thus the electron configuration is [Kr]4d5 5s2
Is chlorine a metal or nonemetal?
Chlorine is a nonmetal. It is only one electron short of a noble gas electron configuration and is much more likely to abstract an electron from some other element than to donate one to some other element.
What element is an alkaline earth metal whose electron configuration ends in 6s2?
All alkaline earth metals have electron configurations ending in s2; 6s2 would be the alkaline earth metal in period 6 of the PTE, which is barium.
What happens to a electrons in a metallic bond?
An element tries to get the stable electronic configuration of the nearest noble gas. If a metal has 1 or 2 or 3 valent electrons, they donate these valent electrons to the non-metals which are deficient of 1 or 2 or 3 electrons. So the extra electron in metals get transferred to the outermost shell of the non metal.

What is the element with the first alkalia metal with a completed 3p?
It would be potassium (K). Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1.
Which group does the electron configuration 1s2 2s2 sp6 3s2 3p6 3d1 4s2 belongs to?
Transition metal and is a d-block element. :) ~Scandium~
What element has 2 electrons in its outer shell and 12 in total?
Magnesium. The complete electron configuration is: 1s2 2s2 2p6 3s2 The complete electron arrangement is: 2e, 8e, 2e
