valence electrons
electrons
Those Roman numerals on the periodic table refer to the number of valence electrons in a given group.
The Roman numeral "ii" represents the number 2. In the Roman numeral system, the letters "i" represents 1, and when it is repeated, it indicates addition. So, "ii" is the equivalent of adding two "i"s together to represent the number 2.
The letter on the left indicates the month it was made (for instance A=January and B=February). The roman numeral or number on the right indicates the year it was made.
The smallest 5-digit number is 10000. To get the smallest 5-digit number, we put a 1 in the first column (since we can't start with a 0 or else we'd get a 4 digit number!), then put a 0 in every other column.
electrons
The Roman numeral at the top of a column on the periodic table indicates the number of valence electrons an element in that column has. Valence electrons are the electrons in the outermost shell of an atom and are involved in chemical bonding. Group IA elements have 1 valence electron, Group IIA elements have 2 valence electrons, and so on.
The column number on the periodic table, also known as the group number, indicates the number of valence electrons an element has. Elements in the same group tend to have similar chemical properties due to having the same number of valence electrons.
The number at the top of each column in the periodic table is the group number. It indicates the number of valence electrons an element in that column has, which influences its chemical properties. Elements in the same group tend to have similar chemical behavior due to their shared number of valence electrons.
The group number is an identifier used to describe the column of the standard Periodic Table in which the element appears.
For example the column 17 - halogens.
The atomic number of seaborgium is 106, and it is found in column 6 of a wide form periodic table.
This is the group 1.
Iodine is the element with atomic number 53 on the periodic table.
