All of the Halogens (the second column from the right on the Periodic Table) have 7 valence electrons. This includes
-Flourine
-Chlorine
-Bromine
-Iodine
What else can I help you with?
How many valence electrons are in the element fluorine and do the same for chlorine and bromine?
The number of valence electrons is seven.
How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
How many valence electrons does an element in 5A contain?
5 valence electrons.
The element Mn has how many valence electrons?
In actuality Mn has SEVEN valence electrons, not really 2 as might be predicted. The reason for this is that Mn is [Ar]3d5 4s2, and as a transition element, not only are the 4s electrons available for bonding, but so are those in the d orbital. So, the 5 electrons in 3d and the 2 electrons in 4s are all considered as valence electrons.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How many valence electron does chlorine?
The element chlorine has seven electrons in its valence shell.
How many valence electrons are in the element fluorine and do the same for chlorine and bromine?
The number of valence electrons is seven.
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
Which electron has seven valence electrons?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
How can i look at the periodic table and tell how many valence electrons an element has?
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
What element has 6 valence electrons?
The element with 6 valence electrons is carbon.
Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
How can you tell from an element's number of valence elns whether the element is more likely to form a caor an anion?
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
How many valence electrons does the element F have?
I believe there is 8 electrons in the outer valence
What are Valence elcetrons?
Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determine the reactivity of an element. The number of valence electrons influences the element's properties and behavior in chemical reactions.
How many valence electrons are in the element Neon?
There are 8 valence electrons in the element Neon, as it is in group 18 of the periodic table.
