Valence electrons are the electrons in the outer energy level. Each period shares many similar characteristics, one of which being the amount of electrons in the outer energy level. If you are unfamiliar, the Periods are the Vertical Columns, and Families are the Rows. I hope this helps you.
What else can I help you with?
Your element belongs to the family?
On the peroidic table of elements, the family tells you a brief overview of what kind of element it is. It could be a metal, or gas, and it usually describes what kind of metal (transition) or what kind of gas (noble).
Group numbers on the periodic table help you determine what?
each group of the periodic table consists of elements that resemble each other. for instance Lithium, sodium, potassium, and a few more a grouped together, are called the alkali metals. These are all highly reactive, thus they are in a group. Furthermore group also determines the number of valence electrons are present in some cases. Hope that answered your question.
How many valence electrons are there in an atom of arsenic iodine calcium tin and sulfur?
What kind of question is that lol I don't even know that and I just studyed that last semester lol
How do valence electrons determine an atoms oxidation number?
Valence electrons determine an atom's oxidation number by influencing how easily the atom can lose or gain electrons to achieve a stable electron configuration. The oxidation number of an atom is often determined by the number of electrons it loses, gains, or shares when forming chemical bonds with other atoms. Valence electrons play a key role in this process, as they are involved in the bonding interactions that lead to oxidation number changes.
What kind of bond shares valence electrons?
Covalent bond :)
What kind of elements has less than 4 valence electrons?
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
How do you determine the charge on an element based upon the number of valence electrons?
Because of the octet rule, it is easy to predict the charge of the ion of an element. Look at the number of valence electrons the element has. If it is between 1 and 4 the atom will most likely loose those electrons to become stable, making it a positive ion with the charge of the number of electrons it will lose. If it has between 4 and 8 valence electrons the atom will most likely gain electrons to achieve a full outer ring of 8 electrons. Its atom will have a negative charge of the number of electrons it needs to have 8 total. Eight-APEX James Terrell THE FALLEN ONE- JAMES TFA-The Fallen Angel
What is the trend in the number of valence electrons as you move down a group?
There is no trend for going down a group. The only trend is that valence electrons increase from left to right, across a period. When you move down a group, the number of valence electrons stay constant.(:
Which electrons are shared in molecules?
In metallic bonding, the valence electrons freely 'jump' from atom to atom, forming kind of an electron sea.
What is a synonym for valence electrons?
'Electrons in the atom's outer shell'. There isn't really a synonym for this kind of thing.
When a covalent bond is formed what kind of electrons is used in the bond?
In a covalent bond, the electrons used are typically the valence electrons of the atoms involved. These are the outermost electrons. Each atom contributes one or more valence electrons to form a shared pair in the bond.
How many valence electrons are in a hydrogen ion?
It depends on what kind of ion:If it's a cation (H+) then there is 1 proton and 0 electrons, so zero.If it's an anion (H-) then there is 1 proton and 2 electrons, so 2 (and that shell is full).
