What is a period in a periodic table?
a row going acrossNOT to be confused with groups or families which go down in columns and have to do with valence electrons
Why is important to organize the elements in a periodic table?
It is helpful to organize things by characteristics because you can tell that certain elements are similar. For example if you knew nothing about the chemical or physical properties of (Rb) Rubidium, you could guess it has properties similar to (Cs) Cesium since they are in the same group. The common "Periodic Table" has many interesting forms. Search: "periodic table"
Why do the elements belonging to a particular group exhibit similar chemical behavior?
Elements in the same group have the same number of valence electrons, which dictates their chemical behavior. Valence electrons are responsible for the way atoms interact with each other in chemical reactions. This similarity in valence electron configuration leads to similar chemical reactivity among group members.
Atoms of elements with the same electron configuration are organized in in the Periodic Table?
They are not! It is a prevalent myth that the elements are organized so that elements with the same configuration are organized into the same group, but all that really matters is the number of valence electrons, and that much is guaranteed by the arrangement in order of atomic number.So we have for example in group 10, Ni with configuration [Ar] 3d8 4s2 , Pd with configuration [Kr] 4d10 , and Pt with configuration [Xe] 4f14 5d9 6s1.Group 4 is characterized (supposedly) by the electron configuration d2 s2 but thorium which has this configuration is not placed in this group but in the actinides.
When looking at the periodic table of elements that have the same numbers of electrons?
Elements with the same number of electrons have similar chemical properties because they have the same electron configuration in their outer shell. This leads to similar reactivity and bonding behavior among them. Examples include elements in the same group or column of the periodic table.
Elements in a have similar chemical properties?
a group of elements that have similar properties are arranged one on top of the other on the periodic table. These groups are also called families
What are the familys of the periodic table?
families are vertical columns of elements they have similar chemical and physical properties.
Elements in a column are called . These elements have similar chemical and physical properties.?
These elements have similar chemical and physical properties.
What is a group of 3 elements with similar chemical properties?
Iron , cobalt and Nickel families of periodic table show the similar properties. these families are in three different columns but are considered as one group.
Are elements with similar chemical properties found in the same period or group on the periodic table of elements?
Elements with same properties are found in same group.They are also called families.
Why are the groups on the periodic table also called families?
Groups on the periodic table are called families because elements within the same group share similar chemical properties due to having the same number of valence electrons. This similarity in properties is what defines them as a family.
How many families are in the periodic table?
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
Why are the elements put into the same columns?
Because the elements of the column have similar chemical properties and follow trends in the columns
Why are elements put into families?
Elements are organized into families on the periodic table based on their similar chemical properties. Elements in the same family have the same number of valence electrons, which determines their reactivity and chemical behavior. This organization helps scientists predict the properties of unknown elements based on their location in the periodic table.
What elements on the poeriodic table tend to have similar physical and chemical properties?
Both elements, sodium (Na) and potassium (K) lie in the Group 1 column of the Periodic Table , which contains the members of the Alkali Metals family. Members within a family, or column, of elements tend to have similar chemical properties.
Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
What sets of elements have similar physical and chemical properties?
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
