explain the function of the valence ring
butt head
A full outer ring, or valence shell, has 8 electrons, except for helium, which has 2 electrons.
Neutral Bromine has three complete rings of electrons. The first ring consists of 2 electrons, the second has 8, the third 18, and the fourth has a maximum capacity of 8 electrons. Bromine only has 7 electrons in it's outer ring, though, so it needs one extra electron to complete it's ring. So to answer your question, it needs ONE more valence electron.
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
Cesium has one valence electrons in its outer ring, as indicated by its placement in column 1 of a wide form periodic table or column IA of a narrow form periodic table.
Sodium and chlorine form bonds because of their valence electrons. the sodium atom has one electron on the outer ring, or level, while chlorine has 7. an atom is considered stable if it has 8 valence electrons, and since the two atoms have a total valence of 8, they will form a stable bond.
3 electrons 2 in the first ring 8 in the second ring And 3 in the valence
Oxygen, with a electron number of 8 there are two electrons on the first orbit ring and six an the outer ring(shell) those are the valence electrons
The outer ring of electrons, or the valence electrons.
The electrons in the atom are found on the outer rings, the limit of 2 on the first up to 8 on the valence ring. The number of the electrons found on the valence ring determines where the chemical is placed on the Periodic Table.
A full outer ring, or valence shell, has 8 electrons, except for helium, which has 2 electrons.
Neutral Carbon atoms contain 6 electrons and 6 protons 2 electrons are found in the 1st electron ring and 4 in the outer ring to reach a stable electron (8 in the outershell) arrangement carbon requires 4 covalent bonds to be formed
How many valence electrons it has relative to the other elements in its row (which obviously has other implications which I won't get into). Each row has a specific amount of rings. Row 1 has 1 ring which can hold 2 electrons, thus hydrogen is in the first column with 1 electron in that valence ring and helium with 2 (a full ring). Rows 2 and 3 elements have 2 and 3 ring respectively and each of those rings can hold 8 electrons, thus 8 elements in each row with each successive element having 1 greater electron in that ring (their valence ring) than the previous element. Row 4 has elements which have all the previous rings filled but also start to fill the fourth ring (their valence ring) which now has 18 electrons it can hold. You see where I'm going with this...

Helium had valence electron of 2 and filled the most inner ring so it is chemically robust and inert. Outer valence electron ring contain 8 electrons so for Neon is robust as it had 2,8 electrons and Argon had 2,8,8 electrons and fill the outer ring.
