What does it mean if an elements has 8 valence electrons?
it has a full octet
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
How do valence electrons tell you what elements will bond together?
Valence electrons are involved in bonding between elements because they determine an element's reactivity. Elements with a similar number of valence electrons tend to bond together to achieve a stable electron configuration, either by losing, gaining, or sharing electrons. This interaction allows elements to form compounds with one another.
How many valence electrons in the nean family?
There are 8 valence electrons in the noble gases, the family of elements furthest to the right on the periodic table.
Does krypton have 8 valence electrons?
No, krypton has 8 valence electrons.
What does it mean if an elements has 8 valence electrons?
it has a full octet
How many valence electrons can an atom have?
An atom can have a maximum of 8 valence electrons, except for hydrogen and helium, which can have a maximum of 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many valence electrons does group 8 have?
Group 8 elements, also known as the noble gases, have 8 valence electrons. This is the maximum number of electrons that can occupy the outer shell of an atom, giving them stability and low reactivity.
How many valence electrons do most elements need to become stable?
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
In group 8 on the Periodic Table what element does not have 8 valence electrons?
Iron (Fe) is in group 8 on the Periodic Table and it does not have 8 valence electrons. Iron has 2 valence electrons in its 4s orbital and 6 valence electrons in its 3d orbital, making a total of 8 valence electrons.
What type of elements have valence electrons?
Elements in every group of the periodic table has some number of valence electrons. The exception is, when it comes to group 18, the number of valence electrons might be considered as either 0 or 8.
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
How man valence electrons does neon have?
Neon has 8 valence electrons. This is because neon is in the 8th group (or 18th column) of the periodic table, and elements in this group have a full set of 8 valence electrons.
How many valence elactrons do all the elements in neon's family have?
All elements in neon's family (Group 18/Noble Gases) have 8 valence electrons, except for helium which has 2 valence electrons. This full valence shell makes them stable and unreactive.
In most elements the valence shell holds a maximum of how many electrons?
In most elements, the valence shell holds a maximum of 8 electrons. This is known as the octet rule, where atoms tend to gain, lose, or share electrons in order to achieve a full valence shell of 8 electrons, making them more stable.
How does the number of valence electrons for elements across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
