Group 5A (or VA) of the periodic table are the
pnictogens
: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
Why are Group 5 elements called pnictogens?
Group 15 elements are also known as pnictogens
because in Greek pigeon means to cholk or stifle
. In the absence of the oxygen, molecular nitrogen has this property. That’s why group 15 elements are known as either nitrogen family or pnictogens.
What are group 6 elements called?
| IUPAC group number 6 | Name by element chromium group | CAS group number (US, pattern A-B-A) VIB | old IUPAC number (Europe, pattern A-B) VIA |

What are pnictogens and Chalcogens?
The terms tetrel bond, pnictogen bond and chalcogen bond were coined recently to describe
non-covalent interactions involving group 14, 15 and 16 atoms
, respectively, acting as the electrophilic site that seeks a nucleophilic region of another molecule, for example a non-bonding electron pair or π-electron pair of a …
What is Group 7 called?
The Group 7 elements are called
the halogens
. They are placed in the vertical column, second from the right, in the periodic table . Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals. The term ‘halogen’ means ‘salt former’.
What are Group 4 elements called?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements
titanium (Ti), zirconium (Zr), hafnium (Hf)
, and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.
What is Group 13 called?
Boron group element
, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What is a group of 14 called?
Carbon group element
, any of the six chemical elements that make up Group 14 (IVa) of the periodic table—namely, carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
Why is Group 16 called chalcogens?
-Group-16 elements are also called chalcogens. They are called so
because most of the copper ores have copper in the form of oxides and sulphides
. They also contain small amounts of selenium and tellurium. … So, group-16 elements are named chalcogens.
What is the charge of group 5 elements?
That is, the Group 7A nonmetals form 1- charges, the Group 6A nonmetals form 2- charges, and the Group 5A metals
form 3- charges
.
What are the group 3 elements called?
Group 3A. Group 3A (or IIIA) of the periodic table includes the
metalloid boron (B)
, as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
What are the properties of group 4 elements?

What is Group 16 called?
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).
Is oxygen or selenium more reactive?
In the periodic table, it is the second most electronegative product, making
it the group’s most reactive
. The oxygen group is sometimes called group 16 elements of the periodic table. Nonmetals are the first three elements-oxygen (O), sulphur (S), and selenium (Se).
What is Group 15 called?
Summary. Members of group 15 of the periodic table (15th vertical column) are summarised as group 15 elements (or
the nitrogen group
) consisting of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb) and bismuth (Bi).
