What does it mean if an elements has 8 valence electrons?
it has a full octet
How do valence electrons tell you what elements will bond together?
Atoms only bond if it helps them achieve their goals of having 8 valence electrons. That is why noble gases do not bond; they already have 8 valence electrons.
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 many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
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.
What does it mean if an elements has 8 valence electrons?
it has a full octet
How many valence electrons can an atom have?
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.
How many valence electrons does group 8 have?
Elements in group 8 all have 8 valence electrons, this is why these elements are in group 8, they are called noble gases, some examples are Argon, Xenon,
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 do valence electrons tell you what elements will bond together?
Atoms only bond if it helps them achieve their goals of having 8 valence electrons. That is why noble gases do not bond; they already have 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
What elements have less than eight valence electrons?
Any element except the elements in group 8, 9, 10, 11, 12 and 18 have lesser than 8 valence electrons.
How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
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).
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.
How many valence electrons are found in a krypton atom?
There are 8 Valence Electrons.
