The Group 6A elements are oxygen, sulfur, selenium, tellurium and polonium. The number of valence electrons in Group 6A is 6.
6 x 2 = 12. 4 are part of a double covalent bond; the other 8 form lone/nonbonding pairs.
Group 6A elements in the periodic table (oxygen group) typically have 6 valence electrons, exhibit a -2 oxidation state, and include nonmetals like oxygen, sulfur, selenium, and tellurium. These elements tend to form oxides and have varying physical properties, such as color and reactivity.
To answer this question, refer to the periodic table. You would have to find the 5th column (not including transitional metal). Therefore, the Nitrogen family has 5 valence electrons which is why it has a 3- charge (since 3 more electrons would complete its outer shell). Phosophorus, arsenic, bismuth, and antimony are also included in this family.
Nitrogen is not a member of group 6A. It belongs to group 5A on the periodic table. The other elements - oxygen, selenium, and sulfur - belong to group 6A.
Since Selenium is a Chalcogen (meaning it's in group 6A on the Periodic Table), it gains 2 electrons to form an ion with a charge of -2.
The valence electron configuration for Group 6A elements is ns^2 np^4. This means that Group 6A elements have 6 valence electrons in their outermost shell.
There are 6 electrons in the valence shell of the oxygen family. This includes elements like oxygen, sulfur, selenium, and tellurium. These elements all have 6 valence electrons because they belong to group 16 (or 6A) of the periodic table.
oxygen has 6 valence electrons as indicated by the 6A above the group oxygen is in
Sulfur is part of group 16 of the periodic table because it has 6 valence electrons, which gives it similar chemical properties to other elements in the group. Group 16 elements tend to form compounds by gaining or sharing 2 electrons to achieve a stable electron configuration.
Any of the elements in group 6A would qualify eg Oxygen (O), sulfur (S) etc.. Theirs many answers on the web that tell you diferently but this is correct as it came streight out of my chemistry book! Goodluck!!
Group 2A * Known as Alkaline earth elements * All are metals * Occur only in compounds * React with oxygen in the general formula EO (where O is oxygen and E is Group 2A element)
There are four valence electrons because it is in 4A row. 5A 5 valence 6A 6 valence etc. Carbon has four.
Selenium is found in Group 6A (Group 16) of the p-block because it has six valence electrons, which places it in the 6th group of the periodic table. It shares similar chemical properties with the other elements in Group 6A, such as oxygen and sulfur, due to its electron configuration.
They should gain 2 electrons to attain noble gas electronic configuration. (it doesn't become a noble gas as the number of protons are not same)
Sulfur and oxygen are in the same group (Group 6A) because they have similar chemical properties due to their shared number of valence electrons, which influences their reactivity and bonding behavior. They both have six valence electrons, leading to comparable trends in their chemical properties within the same group.

Group 6A elements have a higher electronegativity and a greater tendency to gain electrons to achieve a stable octet configuration. In contrast, Group 2A elements have a lower electronegativity and typically lose electrons to form cations.
