Question: What Is The Period Number Of Oxygen?

What 3 digits are in the thousands period?

Notice that the digits 3, 0, and 2, are in the thousands period.

This represents “three hundred two thousand”.

In the ones period are the digits 0, 2, and 0, which represent twenty..

What do periods and groups tell you?

D. Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

What are the elements in oxygen?

Under standard conditions oxygen forms a gas that is composed of molecules consisting of two oxygen atoms (O2). This is called a diatomic gas. In this form oxygen is a colorless, odorless, tasteless gas. Oxygen also exists as the allotrope ozone (O3).

What is period and group in periodic table?

A period is a horizontal row of the periodic table. There are seven periods in the periodic table, with each one beginning at the far left. … A group is a vertical column of the periodic table, based on the organization of the outer shell electrons. There are a total of 18 groups.

Who named Oxygen?

Antoine-Laurent LavoisierIn 1775–80, French chemist Antoine-Laurent Lavoisier, with remarkable insight, interpreted the role of oxygen in respiration as well as combustion, discarding the phlogiston theory, which had been accepted up to that time; he noted its tendency to form acids by combining with many different substances and accordingly …

Is oxygen o2 or just O?

The element is O, because the periodic table isn’t describing molecules, it’s describing atoms. The molecule is O2 because it takes 2 O atoms to make a molecule of oxygen. These types of elements are called diatomic elements, because the element exists in its pure form as a molecule composed of 2 atoms of the element.

What is period Number?

A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. … Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law.

What is the group of oxygen?

Professor of Chemistry, University of Minnesota, Minneapolis. 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).

Can oxygen be made?

Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. … This method is called electrolysis and produces very pure hydrogen and oxygen.

Why can’t oxygen have 9 protons?

Oxygen is defined as “an atom having 8 protons in the nucleus.” Atoms having 9 protons in the nucleus are called “fluorine.” An oxygen atom has 8 protons in its nucleus. Why can’t it have 9 protons? Because an atom that has 9 protons would be Fluorine.
