Barium (56)
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
Lithium is the alkali metal that has two energy levels in its electron configuration. Its electron configuration is [He] 2s¹.
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
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
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 electron configuration 1s2 2s2 sp6 3s2 3p6 3d1 4s2 belongs to the group of transition metals. It is the electron configuration of the element titanium (Ti), which is a transition metal with atomic number 22.
Fluorine is the most reactive non-metal element. It readily gains an electron to achieve a stable electron configuration, making it highly reactive.
You think probably at Unbinilium (120Ubn) an element not still obtained. The supposed electron configuration of Ubn will be [Uuo]7s2.
The electron configurations of H, Li, Na, K, Rb, and Cs are similar in that they all have one valence electron in their outermost energy level. These elements belong to the alkali metal group in the periodic table and tend to exhibit similar chemical properties due to their outermost electron configuration.
Cs (cesium) is most likely to donate one electron as it is classified as an alkali metal with a single valence electron in its outermost energy level.
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
The element with the electron configuration 1s²2s²2p⁶3s²3p²4p¹ is indium (In). Indium is located in group 13 of the periodic table and has an atomic number of 49. It is a post-transition metal known for its use in electronics and alloys.
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
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.
