What are group 16 elements called?
chalcogen
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).
Which electron configuration belongs to oxygen?
In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the O electron configuration will be 1s22s22p4.
What is a group of 17 called?
In the modern IUPAC nomenclature, this group is known as group 17. The name “halogen” means “salt-producing”. The group of halogens is the only periodic table group that contains elements in three of the main states of matter at standard temperature and pressure. All of the halogens form acids when bonded to hydrogen.
What is the full electron configuration for O?
[He] 2s² 2p⁴

What is the electronic configuration of oxygen?
The electron configuration of the element Oxygen is 1s2 2s2 2p4
How to calculate electron configuration?
Method 3 of 4: Using an ADOMAH Periodic Table Understand the ADOMAH Periodic Table. This method of writing electron configurations doesn’t require memorization. Find your atom in the ADOMAH table. To write electron configuration of an element, locate its symbol in ADOMAH Periodic Table and cross out all elements that have higher Count orbital sets up to your atom.
What is the electron affinity of oxygen?
Electron Affinity of Oxygen is 141 kJ/mol. Electronegativity of Oxygen is 3.44. In chemistry and atomic physics , the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.
What is the atomic configuration of oxygen?
Atomic number of oxygen is 8, so it has total 8 electrons. In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital.
