What are the horizontal rows on the periodic table called?
The horizontal rows on the periodic table are known as Periods.
How many energy shells does period 2 have?
All the elements of period 2 have two energy shells (or orbits).
Why are period 4 and period 5 called long periods?
Period 4 and period 5 are given the name long periods of the periodic table because there are 18 elements in these periods. The elements of the long periods are shown in tables below.

How to read the periodic table?
To read the periodic table, start at the top left with the elements with the lowest atomic numbers, which tells you how many protons each atom has. Then, as you move right across the chart, make note that the atomic weight, shown at the bottom of the square, also increases.
How are elements ordered?
The elements are ordered by their atomic numbers, which increase as you move across and down the periodic table. The atomic number is how many protons the element’s atom possesses. You’ll also notice that each element’s atomic mass increases as you move across the table.
Why does the periodic table have gaps?
Since elements don’t always fall neatly into groupings as they increase in number, the periodic table contains gaps. For example, the first 3 rows have gaps, as the Transition Metals don’t appear on the table until atomic number 21.

What is the electron configuration of oxygen?
Electron configuration of Oxygen is [He ] 2s2 2p4.
How many protons does oxygen have?
Oxygen is a chemical element with atomic number 8 which means there are 8 protons and 8 electrons in the atomic structure. The chemical symbol for Oxygen is O.
What is the charge of an atom?
Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. In a neutral atom there are as many electrons as protons moving about nucleus. It is the electrons that are responsible for the chemical bavavior of atoms, and which identify the various chemical elements.

Which gases have high thermal conductivity?
The mean free path also depends on the diameter of the molecule, with larger molecules more likely to experience collisions than small molecules, which is the average distance traveled by an energy carrier (a molecule) before experiencing a collision. Light gases , such as hydrogen and helium typically have high thermal conductivity. Dense gases such as xenon and dichlorodifluoromethane have low thermal conductivity.
