valence electrons
Valance electrons.
The number of electrons.
Based on the number of valency electrons.
On the peroidic table of elements, the family tells you a brief overview of what kind of element it is. It could be a metal, or gas, and it usually describes what kind of metal (transition) or what kind of gas (noble).
Atomic number is the characteristic used to place the elements in their rows. Electron configuration is another characteristic that governs which elements are placed in groups.
A periodic trend is a regular variation the properties of an element with increasing atomic number.
Families in the Periodic Table of Elements have the same amount of valence electrons.
They have the same amount of valance electrons.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
The properties of elements are periodic function of their atomic number. The properties are repeated after certain interval.
yes
Is the same thing as a family and a family is a vertical column in the periodic table. Elements in a family all share similar characteristics, whether they be physical or chemical. There are 18 family (or group) columns in the periodic table.
Each family has different number of valence electrons. The chemical properties of each family is also different.
Elements are arranged by their atomic number. The properties are periodic when arranged in this manner.
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
according to increasing atomic number and repeating periodic properties.
On the peroidic table of elements, the family tells you a brief overview of what kind of element it is. It could be a metal, or gas, and it usually describes what kind of metal (transition) or what kind of gas (noble).
Atomic number is the characteristic used to place the elements in their rows. Electron configuration is another characteristic that governs which elements are placed in groups.
One of the characteristic properties of an element is that consists of atoms that has the same number of protons. The other characteristic is that it has a distinctive atomic number. The last characteristic is that it cannot be decomposed in the chemical reaction.
