No. Lithium is an alkali metal (or group 1 element).
Lithium is not a noble gas. But Li+ will have the same number of electrons as the noble gas, helium.
Yes, the elements in group 18 are noble gases.
lithium is an alkali metal
Thorium is a radioactive metal.
[He] 2s1
[He] 2s1
[He]2s1
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
Lithium is not a gas but solid metal
Sort of. Lithium loses one electron in order to achieve the noble gas configuration of helium, which has only two valence electrons in its 1s sublevel. The octet rule refers to the fact that atoms share or transfer electrons in order to achieve a noble gas configuration with eight valence electrons, called an octet. Helium is an exception to the rule.
Lithium is in group 1 of the Periodic How_many_electrons_must_the_lithium_atom_give_up_to_become_stable, so it must lose one electron for it to attain a full outermost energy level and become stable.The charge will then be positive (+).
The electron configuration of fermium is [Rn]5f12.7s2.
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.
[He] 2s1
The electron configuration of americium is [Rn]5f7.7s2.
A Nobel gas, or an atom with a filled valance shell. In Nobel gas configuration.
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======
[Xe] 4f3 6s2
No - but the potassium ion does
It is [Kr] 4d2 5s2
.. [Li]+ [:I:]- (put the last 2 pairs above and below the "I" this wont let me) ..
[Xe] 4f3 6s2
[He] 2s1
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
