What group have element that has the electron configuration 1s22s22p63s23p63d14s2?
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
How many electrons does potassium need to gain or loose to become more stable?
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 first element in a period is always an active?
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.
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 alkali metal has two energy levels?
Lithium is the alkali metal that has two energy levels in its electron configuration. Its electron configuration is [He] 2s¹.
What group have element that has the electron configuration 1s22s22p63s23p63d14s2?
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
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.
Which group does the electron configuration 1s2 2s2 sp6 3s2 3p6 3d1 4s2 belongs to?
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.
Which element is the most reactive non metal?
Fluorine is the most reactive non-metal element. It readily gains an electron to achieve a stable electron configuration, making it highly reactive.
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.
In what ways are the electron configurations of H Li Na K Rb and Cs similar?
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.
Which electron configuration indicates a neutral transition metal element?
A neutral transition metal element typically has an electron configuration that includes partially filled d-orbitals, which is characteristic of transition metals. These elements are found in groups 3 to 12 of the periodic table and often have an electron configuration that can be represented as [noble gas] ns² (n-1)d⁴ to (n-1)d¹⁰, where "n" is the principal quantum number. For example, iron (Fe) has the electron configuration [Ar] 4s² 3d⁶, indicating it is a neutral transition metal with a partially filled d-subshell.
Which element is most likely to donate one electron Be Cs Rn or He?
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.
How many electrons does potassium need to gain or loose to become more stable?
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.
What element has the electron configuration 1s22s23p24p1?
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.
How many valence electrons does the element cesium have?
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.
The first element in a period is always an active?
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.
