Which elements have electron configurations that end in NS 2 NP 5?
The elements of Group 17 (fluorine, chlorine, bromine, iodine, and astatine) are called the halogens. The halogens all have the general electron configuration ns2np5, giving them seven valence electrons.
What does ns1 mean in chemistry?
Explanation: 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.
Which group in the periodic table contains elements with the valence electron configuration of NS 2 NP 1?
Within each column, each element has the same valence electron configuration—for example, ns1 (group 1) or ns2np1 (group 13).
What is ns2np2?
Key Points. The general outer electronic configuration of group-14 elements is ns2np2. Group 14 in the Periodic Table is known as the Carbon Group and there are six elements in this group. Their outermost shell has 4 electrons.
What are NS electrons?
For transition metals, the number of valence electrons ranges from 3-12 electrons (ns and (n−1)d orbitals). For lanthanides and actinides, the number of valence electrons ranges from 3-16 electrons (ns, (n−2)f and (n−1)d orbitals).
Which element is located in the family represented by NS 2 NP 3?
nitrogen
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number. The nitrogen family includes the following compounds: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi).
What family does NS1 belong to?
alkali metals
s-Block Elements: The elements of Group 1 (alkali metals) and Group 2 (alkaline earth metals) which have ns1 and ns2 outermost electronic configuration belong to the s-Block Elements. They are all reactive metals with low ionization enthalpies.
Which elements contains 2 valence electrons?
A: Calcium is a group 2 element with two valence electrons.
How many valence electrons are in the group that includes elements NP and as?
The Group 5A elements have five valence electrons in their highest-energy orbitals (ns2np3). Nitrogen, phosphorus, and arsenic can form ionic compounds by gaining three electrons, forming the nitride (N3-), phosphide (P3-) and arsenide (As3-) anions, but they more frequently form compounds through covalent bonding.
