The general electronic configuration ns2np3 holds true for the Nitrogen family which are the group 15 elements. These include Nitrogen, Phosphorous, Arsenic, Antimony and Bismuth.
What is ns2np1?
Ans: This is an outermost electronic configuration of an atom. And the atom belongs to 13th group. In ns2np1 : n -stands for nth shell. s2: stands two s subshell -electrons. p1: stands for one p subshell -electron.
What is ns2 in chemistry?
ns2 np2 indicates that elements belong to the p-block element having 2 electrons in the outermost shell. Hence, elements of IVA or 14th group have this configuration. Carbon, Silicon, Germanium, Tin, and Lead.
What element is ns2np5?
Detailed Solution. The elements of Group 17 (fluorine (F) – 9, chlorine (Cl) – 17, bromine (Br) – 35, iodine (I) – 53 and astatine (At) – 85) are called the halogens. The halogens all have the general electron configuration ns2np5, having seven valence electrons.
What is ns1 electron configuration?
The general form for the electron configuration of each alkali metal is ns1, where the n refers to the highest occupied principal energy level. For example, the electron configuration of lithium (Li), the alkali metal of Period 2, is 1s22s1.
Which element is found in a family with the electron configuration ns2np3 where n represents the principal quantum number the energy level?
The nitrogen family includes the following compounds: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is equal to the principal quantum number.
What information does the period Number give about an atom’s electron configuration?
Electron Shells
As an atom’s atomic number increases, its shells must accommodate an increasing number of electrons. The outermost shell is called the valence shell; the period number refers to this shell.
What do valence electrons participate in?
Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair.
Which has a larger atomic radius mg or BA?
Magnesium’s atom is smaller than barium’s atom and barium has more shielding than magnesium. This increased shielding counteracts barium’s greater number of protons in the nucleus. The increased shielding and increase in atomic radius gives barium a smaller effective nuclear charge when compared to magnesium.
Which element has the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p²?
Germanium has the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p².
What is the screening effect of d electron?
The screening effect of d- electrons is less than p – electrons. The order of screening effect of s, p, d and f electrons is s > p > d > f. Hence, the screening effect of d-electrons is less than that of s and p electrons.
What is Group 17 called?
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
Which group is known as Chalcogens?
oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
Why is chlorine a halogen?
The elements of Group VIIA (new Group 17 – fluorine, chlorine, bromine, iodine, and astatine) are called the halogens (tan column). The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts.
What group does ns1 belong to?
In an electron configuration under the general form of ns1 , the n represents the period number and the 1 represents the group number, and therefore, the element would be in group 1.
What group ends with ns1?
groups 1A-7A are called the meaning that the s and p sublevels of their outermost principal energy levels are only partially filled with electrons. all elements in this group have an electron configuration ending in ns1.
