The Group 6A elements are oxygen, sulfur, selenium, tellurium and polonium. The number of valence electrons in Group 6A is 6.
6
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.
tabalu..:)
nitrogen
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.
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.
Sulfur is part of column 16 or group 6A because, all elements in group 6A have 6 valence electrons. Sulfur has 6 valence electrons.
oxygen has 6 valence electrons as indicated by the 6A above the group oxygen is in
The elements in group 6a (16) have six valence electrons. The valence electron configuration is Xs2Xp4 , where X is the main energy level (period number).
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!!
There are four valence electrons because it is in 4A row. 5A 5 valence 6A 6 valence etc. Carbon has four.
they are in the same group "6a" because they have the same number of Valence electrons
Because it has same number of valence electrons in the same energy level.
Both have six valance electrons. That is what the number at the top of their column means.
elements of group 6 - colloum 10 gain 2 valence electrons when they form ionic bonds
ClO2− = 7+6(2)+1=20-------------------------------------------------------------Cl= in group 7A=7O= in group 6A=6---------------------------------------------------------------Add +1 = because we have one (-) negative charge.
All of the elements in Group 16 (Group 6A) have 6 valence electrons. Their atomic numbers are 8 for oxygen, 16 for sulfur, 34 for selenium, 52 for tellurium, 84 for polonium, and 116 for ununhexium.
It is alternatively called the Carbon family.
