The last energy level that holds the valence electrons

explain the function of the" "valence ring

Valence electrons are electrons in the outermost ring of an atom.

3 electrons 2 in the first ring 8 in the second ring And 3 in the valence

There are 3 valence electrons in Boron..Remember valence electrons are in the outer shell

Valence electrons are the electrons in the outer ring, or "electron shell" of an atom.

8. Valence electrons are the outer ring of electrons. Once you get to 8 you start a new ring. There are some instances when this is untrue, but as a rule the answer is 8

The outer ring is either n=the number of ring it is, or just plain say "the outer shell." The proper term is VALENCE, the outermost shell = valence shell, outermost electrons = valence electrons

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.

Proximity and valence electrons

It represents the group it belongs to in the periodic table. Valence electrons are the electrons from the last ring.

Ya it has 8.The first ring has 2,8,8

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.

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.

A full outer ring, or valence shell, has 8 electrons, except for helium, which has 2 electrons.

Rubidium only has one valence electron in its fifth ring. That places it in the first column of the periodic table, and it is a an alkaline metal.

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...

Valence electrons are the outermost ring of electrons that are shared between atoms to form covalent bonds or exchanged to form ionic bonds

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.

each period (row) on a periodic table represents the outermost ring of electrons (valence electrons). Well if you count across a period you will get the number of valence electron. For example, if you count across a period for Oxygen (O atomic number:8) you will count 6 which is the amount of valence electrons in oxygen

The amount of valence electrons in an atom of an element is the amount of electrons placed at the outermost ring of the atom.

oxygen is in group 6, and has 8 as that valence thingy. so its 2 in the first rign and 6 in the outer ring.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

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.
