Why iodine must appear in group 7 in the periodic table?
Iodine appears in group 7 of the periodic table (halogens) because it has 7 valence electrons. This property makes it chemically similar to other elements in the group, such as fluorine, chlorine, and bromine. Grouping elements with similar chemical properties helps in organizing the periodic table.
Why do individual isotopes not appear on the periodic table?
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
What are the periodic table?
Periodic table comprises of elements arranged in rows and columns.So that the elements having similar properties appear together.
Do Atoms have no overall eletric charge?
Elements, as they appear on the Periodic Table, have no net charge. They all have equal numbers of protons (+) and electrons (-). HOWEVER, an atom can gain or lose electrons, which will change its charge, but, again, on the periodic table, they all have 0 charge.
What does NO mean on the periodic table?
The only thing it might mean would be number, but that is usually no. and not NO. NO would be nitrogen oxide (nitric oxide), but that would NOT appear in the periodic table, as it is a compound, and only ELEMENTS appear in the periodic table.
Why s block elements are colourless?
s block elements are colorless because they do not have any unpaired electrons in their atomic orbitals to exhibit color. The absence of unpaired electrons means that these elements do not absorb visible light in the wavelength range that corresponds to color perception. As a result, s block elements appear colorless to the human eye.
Why do elements with similar properties appear at regular intervals in the periodic tabele?
Elements with similar properties appear at regular intervals in the periodic table because of their similar electron configurations. As you move across a period, the number of electrons in the outer shell increases, leading to similar chemical reactivity. Additionally, elements in the same group have the same number of valence electrons, which influences their properties.

Where do the elements that are good thermal and electrical conductors appear on the periodic table?
These elements are metals, to the left.
Where is the transuranium elements located on the periodic table?
Transuranium elements are elements that appear after uranium. Elements with atomic number 93 to 103, appear in the actinides whereas elements with atomic number 104 to 118 appear in the 7th period.
Do the oldest know metallic elements appear at the beginning of the periodic table?
No, it is not true.
What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
What are the periodic elements and their symbols?
All elements appear in the periodic table, there are more than 100 of them, so please look at the related link below to see an example of such table and all symbols of them.(Please note that there is no special group of 'periodic' elements)
Is a gum Arabic a element?
No, if whatever you are looking for does not appear on the Periodic Table of Elements then it is not an element.
