The letter symbols on the Periodic Table represent elements. They are initialisms or abbreviations of the element names, or of their historic, Greek, or Latin names.
For example
Gold is Au (aurium)
Potassium is K, from kalium (Latin)
Mercury is Hg, from hydrargyrum (Latinized Greek for liquid silver)
Tungsten is W for wolfram, an alternate name
They are the same as saying the columns of a periodic table.
The rows on the periodic table are called periods and the columns are called families
each group in the periodic table has there own name, for example the metals is one group. overall there are 5 groups on the table.
It groups elements by repeat free elèctròns which often show in valent or oxidation state. Each row is a new shell. Each block is a new subshell. Each entry is a new orbital.
number of electrons in the elements of this certain group (column)
Groups are vertical columns which represents number of valence electrons. Periods are horizontal rows that represents number of shells of an element.
a family is a column of elements a period is a row of elements
Oxygen is in Period 2 , Group 16 ( VI A) of periodic table
Silicon is located in group-14 and period-3. It is colored differently to represent that it is a metalloid.
Lithium is in the second period and the first group in the Periodic Table of Mendeleev.
Xenon is a noble gas. It belongs to group 18 and period 5 on the periodic table.
It is in group 18 of the periodic table
a family is a column of elements a period is a row of elements
Sodium, Na, is in group 1 period 3 on the periodic table.
group four in the periodic table is a carbon group
Lead is in the group 14 of the Periodic Table.
Lead is in the group 14 of the Periodic Table.
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
Silver is in the period 5 and group 11 of the periodic table.
Hydrogen is located in Group 1A of the Periodic Table.
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
