Valency depends upon no of electrons in outer most shell the atoms have a specific no of electrons in valence shell so they have characteristic valence .(but transition metal violate this rule).

What can you tell about the properties of this element?
The periodic table can be used to quickly determine characteristics (number of valence electrons for example) of an element.
What characteristic of an element determines how its atoms can bonds with other?
The number of valence shell electrons will generally determine the bonding characteristics of the element in question.
Do elements in each group have similar characteristics?
Yes. Every element in a group has the same number of valence electrons.
Pick the statement that is most likely to be true of an element with LOW electronegativity?
The valence electrons of the element are very shielded. The valence electrons are far from the nucleus.
What is the number of valence electrons (number in the outer most energy level)?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
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.
What element is nonreactive but only has 2 valence electrons?
Helium, it is the most inert gas (element ) of all.
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
How is an element's most likely oxidation state related to its valence electrons?
It indicates how many electrons are required to complete a full valence shell.
What info can you learn about an element from the periodic table?
You can find out the symbol, name, mass, state, protons, neutrons, electrons, electronegativity, valence electrons, charge, and many other characteristics of the element considering the characteristics of other elements in the same group or period.
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
