The periodic table is a masterpiece of organised chemical information and the evolution of chemistry's periodic table into the current form is an astonishing achievement. The International Union of Pure and Applied Chemistry (IUPAC) confirmed the names of elements 113, 115, 117, and 118 as: Nihonium (symbol Nh), for element 113.Web
The lanthanides are the 14 elements from cerium (atomic number 58) to lutetium (atomic number 71). The word comes from the Greek "(lambda alpha nu theta alpha nu epsilon iota nu )" meaning "to be hidden". The name probably arose because these elements all hide behind one another in the periodic table.Web

The third major category of elements arises when the distinguishing electron occupies an f subshell. The first example occurs in the case of the lanthanoids (elements having atomic numbers between 57 and 71).The lanthanoids have the general electron configuration [Kr]4d 10 4f i 5s 2 5p 6 5d 0 or 1 6s 2. where i is a number between 0 and …Web
natural abundance of 60.11%, and Ga-71. Use the atomic mass of gallium from the periodic table to find the mass of Ga-71. 1. We know that since there are two isotopes, the relative abundance of each one has to combine to . - 60.11% = 39.89% Ga-71 2. We have to convert the percentages to decimal points before inputting it into the equation.Web

A row on the periodic table is called a period. There are seven periods on the periodic table. You might look and think "wait, I counted nine", and that would be technically wrong because those bottom two rows with elements 58-71, and 90-103 are actually from rows (periods!) 6 and 7 from the main table above them.Web

A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).Web
Electron Configurations and the Periodic Table. As described earlier, the periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table (Figure 6.29), we also see a periodic recurrence of similar electron ...Web
Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H.

In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).Web
