The valence electrons influence many properties and characteristics of a material. The properties of a material which are influenced by the valence electrons are chemical properties, electrical conductivity, some mechanical properties, the nature of inter atomic bonding, atom size, and optical characteristics.

∙ 13y agoValence electrons are electrons that can be shared in the outer shell, also known as the valence shell. When shared, they form covalent bonds with other atoms. For example, two atoms of hydrogen, each missing one valence electron, can share the two extra valence electrons with oxygen, forming water, H2O.

What are valence electrons and shells?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
What is the significance of the number of electrons on the valence shell?
It is important as you can use the number of valence electrons of an element to compute a variety of calculations and also for some other things, such as drawing some chemical structures. For example, you must know the number of valence electrons to draw a Lewis structure of a molecule and also to calculate the formal charge.
What is a chemical property of a metal?
Metals are hard, malleable, ductile and shiny. They're good conductors of heat and electricity and are solid at room temperature with the exception of Mercury which is a liquid. Also, metals usuallyhave high boiling and melting points.
What are some meteor physical properties?
The physical properties of the meteors are that they are rocky and parts of other asteroids.
Do isotopes with the same elements have the same physical properties?
The physical properties are of course different. The chemical properties are considered identical but this is not a general rule; for example hydrogen isotopes (1H and 2H) have some different chemical and biochemical properties.
What can you predict from an elements place in th periodic table?
its valence electrons, its number of energy levels, how reactive it is, and some properties it has
Why can iodine can be substituted for bromine in some compounds?
Because they share similar quality, properties, and have the same amount of valence electrons.
Group 1A elements have similar properties because they?
have the same number of valence electrons, need the same number of electrons to fill their valence shells
What are families in the periodic table that share similar properties?
Some share the same amount of valence electrons. Some could be classified in the same group such as metals, Nonmetal, Metalloids.
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 can one show that elements that have different appearances have similar chemical properties?
You can experiement with the melting point, boiling point, and freezing point of the elements to prove they have similar properties. This and you can check the different physical and other chemical properties for similarities and comparison.
What are five ways that the periodic table can be useful in chemistry?
It can be used to identify some chemical properties of the elements. It helps to find out the relative atomic sizes of the elements. The number of valence electrons, the number of energy levels can be found.
Do Atoms of elements in the same group have the same number of electrons in their outer layer?
Atoms with the similar characteristics or properties are found in the same group or chemical family on the periodic table. Groups are elements in the same chemical family. Within the same group elements have the same number of valence electrons which determines their chemical properties. Here are some characteristics of some of the groups:
What can you determine about an about an element if you only know its group number on the periodic table?
how many electrons it has in its valence shell usually also some of the characteristics... eg. alkali metals vs. noble gases etc.
What are valence and electrons?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are 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 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,
