The first Periodic Table was a handwritten table by Mendeleev. It had groups horizontally across the top and periods down the left hand side. The elements were all put into certain groups with only their chemicals symbols and atomic numbers depicted.

How was mendeleevs periodic table like todays periodic table?
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
When was copper added to the periodic table of elements?
Oh, dude, copper has been chilling on the periodic table since way back in the day. It was discovered way back in ancient times, like before Wi-Fi was even a thing. So yeah, copper has been part of the elemental squad for a looong time.
What is one property that you can't find on the periodic table?
The physical properties are not listed in periodic table. The properties like density is not listed.These can't be found on periodic table.
What does NCS molecule stand for on periodic table?
Periodic table lists elements and any species like NCS like the one asked in the question.
Who was the scientist responsible for the first periodic table?
To study elements many attempts were made to classify the elements.Dobereighner tried to arrange the elements int groups of three and called them as Dobereighner' triads.Newland also categorized the elements in groups of eight like the musical notesand called them Newland's octaves.But the most credited person for creation of periodic table was Dimitry Ivanovich Mendeleev who arranged the elements on the basis of increasing atomic massesand made an actual periodic table placing all the discovered elements discovered at that time. Not only that, he also left spaces for future elements to be discovered.But there were some defects in his table which were corrected by Henry Mosleywhen he formed the modern periodic table based on increasing atomic number.

What did Mendeleevs periodic table look like?
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.

What does family mean in the periodic table?
a family of the periodic table is like a group of elements of the same type.
