Group VII elements, also known as the halogens, are highly reactive nonmetals. They have seven valence electrons and tend to form -1 anions by gaining one electron. They exist in various physical states at room temperature, from gases like chlorine and fluorine to solids like iodine.

What is the general electron configuration for the anion formed from a neutral atom of any group VII element?

The general electron configuration for the anion formed from a neutral atom of any group VII element (halogen) will be [noble gas] ns^2 np^6, where the noble gas represents the previous noble gas in the periodic table. This is because group VII elements typically gain one electron to achieve a full outer shell of 8 electrons, forming a stable negative ion.


What special names are given to the group you group vii and group viii elements?

What are the combining ratios of elements in group II with elements in Group VII of the periodic table?

The combining ratio for Group II elements with Group VII elements is 1:2. For example, calcium (Group II) will combine with chlorine (Group VII) to form calcium chloride with a ratio of 1 calcium atom to 2 chlorine atoms.

Why is helium placed in group vii?

Helium has a full outmost valence shell. It is a nobel gas. it doesn't react with other chemicals. because the atomic number is 2 so it has to be in group 18 as it also has noble gases.

In which group do the elements ussually orm oxides which have the general formula M2O3?

Group 3(III) Oxides of Group (I) are M2O Group (II) are MO Group(III) are M2O3 Group(IV) are MO2 Group(V) are M2O5 ( Can vary ; NO , N2O , NO2) Group(VI) are MO3 ( Can Vary ; MO2 MO3) Group(VII) are M2O7 ( Can Vary) Group(VIII) are ther Noble (Inert) gases and do not react. Transition metal/elements can exhibit variable oxidations from MO , M2O3, etcs., NB Group (V) , (VI), & (VII) have variable oxidation numbers and so can exhibit various oxides. NNB 'M' is used to indicate an element , not just a metal .
