1. Oxygen is the first member of the group VIA and sulphur is the second member of the group VIA. 2. Other member of this group are selenium, tellurium and poloniu..

Oxygen - Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it consti..

There are seven periods in the periodic table and each period starts with a different principal quantum number. The first period corresponding to 'n' = 1 consists of only two elements hydrogen (1s 1 ) and helium (1s 2 ). This is because t..

. They have four, five, six and seven valence electrons. The elements of group VA, VIA and VIIA can accept 3, 2 or 1 electrons in their valence shell to attain the configuration of nearest noble gas. They become negatively charged i.e. Anion..

1.Chlorine is placed second after fluorine in group VIIA. 2. Other members of this group are fluorine, bromine, iodine and astatine (the last member is radioactive). 3. Members of this group are called 'halogens' meaning salt producers. 4. Atoms of halogens have seven electro..

The position of an element in the periodic table is generally determined by its electronic configuration e.g. electronic configuration of sodium is 2, 8, 1 i.e., it has three shells and one electron in the outermost shell. Hence, it is placed in period number..

Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations. ..

Allotropy in Sulphur - A chemical element is said to exhibit allotropy when it occurs in two or more free forms in the same physical state; the forms are called allotropes. Allotropes generally differ in physical properties such as color and hardness; they may also differ in molecular str..
