No, because as the days and years go past, more scientists will find out more information on the Periodic Table. When they find out information on the periodic table, sometimes new elements are found, adding new elements on the periodic table causes it to change.
What else can I help you with?
What are characteristics of periods in the periodic table?
Periods have same shells. There are 7 periods in periodic table.
What is the definition of block in periodic table?
In the periodic table elements having valence electrons in the same orbital are said to be placed in the same block.There are four blocks in the periodic table s, p, d and f.
Is Within a family on the periodic table the number of electrons on the valence level is always the same true of false?
The elements in each column of the periodic table have the same number of valence electrons. None of the other characteristics listed in the question is common to all these elements.
How do you find protons without electrons?
The number of protons is always the same as the atomic number. If you have a periodic table, then you will always know how many protons are in each element.
How can you identify the elements in a family on the periodic table?
Elements in the same family on the periodic table have similar chemical properties and characteristics due to their shared number of valence electrons. They are located in the same column on the periodic table and have the same number of valence electrons, which influences their reactivity and bonding behavior. The main group elements in the periodic table are organized into families based on their electron configuration, with each family exhibiting similar properties.
When an atom becomes an ion does it affect its posistion in the periodic table?
No, absolutely not. The ion still has the same number of protons, which determines the element's position on the periodic table. The periodic table always stays the same.
In the periodic table what is a period?
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Where do you look on the periodic table to find an element with properties similar to that of another element?
In the same column.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
Are families and groups the same in meaning in the periodic table of elements?
yes, families and groups the same meaning in the periodic table.
What are characteristics of periods in the periodic table?
Periods have same shells. There are 7 periods in periodic table.
What does family mean in the periodic table?
a family of the periodic table is like a group of elements of the same type.
Do elements all have the same mass?
No, look at any periodic table and you will see they are arranged in order of increasing mass.
What is the definition of block in periodic table?
In the periodic table elements having valence electrons in the same orbital are said to be placed in the same block.There are four blocks in the periodic table s, p, d and f.
Is Within a family on the periodic table the number of electrons on the valence level is always the same true of false?
The elements in each column of the periodic table have the same number of valence electrons. None of the other characteristics listed in the question is common to all these elements.
How do you find the mass of hydrogen?
Look on a periodic table. If you have different isotopes then you need to multiply the mass number and atomic number and then find the average of them and you'll have the average atomic mass which is the same as on the periodic table. The location of the mass number on a periodic table depends but it's normally the one with a decimal.
Mendeleev arranged his periodic table into horizontal rows by what criteria?
Atomic Mass. Later on, we discovered that the transition metals did not always have the same mass, which made it difficult to rely on is periodic table. we now arrange it by atomic number.
