What is Group 17 also known as?
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).
What is Group 15 called?
Nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
What is be in periodic table?
Beryllium – Element information, properties and uses | Periodic Table.
Why is Group 16 called Chalcogens?
The group VIA elements are called chalcogens because most ores of copper (Greek chalkos) are oxides or sulfides, and such ores contain traces of selenium and tellurium.
Which group is called Chalcogens?
The chalcogens (/ˈkælkədʒɪnz/) are the chemical elements in group 16 of the periodic table. This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po).
What are Group 16 elements 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).
What is s 16 on the periodic table?
SulfurSulfur is a chemical element that is represented with the chemical symbol “S” and the atomic number 16 on the periodic table. Because it is 0.0384% of the Earth’s crust, sulfur is the seventeenth most abundant element following strontium.

Are all actinides synthetic?
All actinides are radioactive and release energy upon radioactive decay; naturally occurring uranium and thorium, and synthetically produced plutonium are the most abundant actinides on Earth. … The other actinides are purely synthetic elements.
What does K stand for on the periodic table?
PotassiumThe name is derived from the english word potash. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. Potassium is a soft, silvery-white metal, member of the alkali group of the periodic chart.
Why is Group 15 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.

Why is it called the S block?
The s-block and p-block elements are so called because their valence electrons are in an s orbital or p orbital respectively. They are also called Typical Elements to distinguish them from the transition and inner transition series.
What is the most electronegative element in Group 16?
oxygenThus in reactions with metals, they tend to acquire two additional electrons to form compounds in the −2 oxidation state. This tendency is greatest for oxygen, the chalcogen with the highest electronegativity.

Is the first element of Group 16?
Answer. Oxygen (O) is the first element of group 16 .
Is P on the periodic table?
Phosphorus is a chemical element with the symbol P and atomic number 15.
What are 3 trends in the periodic table?
Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element’s properties.
