"It's our first evidence that we can use to confidently state that torium is made in kilonova when two neutron stars merge, filling in another blank on the periodic table."
"Cobalt's an element in the periodic table of course but which sits right in the center amongst the transition metals in fact it sits next to iron and in some ways it shares a lot of characteristics with it."
"The periodic table isn't a rule of nature, it is a handy way for us to perceive the elements as we find them in the universe."
"Every element has its own particular properties."
"Predictions can be made from the gaps in a periodic table for the discovery of missing elements."
"...elements in the same group have similar properties...Group one elements react with water with increasing vigor as you go down the group..."
"Make sure you can describe that if they ask you in the exam about atomic radius it's the increasing number of protons and similar shielding there's no extra shells being added as we go across the period."
"I counted to 20 and started reciting the elements of the periodic table to center myself."
"...transition metals in the middle have the most unpaired electrons."
"...the whole periodic system is really a consequence of the quantum numbers that attach to the orbits and an ability to count."
"Elements in the same group on the periodic table have similar chemical properties."
"The beauty of the periodic table is you have trends that relate pervasively."
"The periodic table... is a chart showing all the different kinds of atoms."
"The periodic table tells us so much; it's going to become much easier in chemistry if you understand lots about it."
"The rules for working out a molecule's shape involve the group of the central atom in the periodic table."
"The periodic table actually acted as sort of a testing ground for atomic theories for about 50 years."
"Electronegativity increases towards fluorine on the periodic table."
"The periodic table tells us a lot about chemicals."
"The reason the columns are called groups is that we group together things that have similar properties."
"Our good old friend Dmitri Mendeleev, the fellow who invented the periodic table, had some interesting problems with his table."
"By the end of this chapter, you will be able to describe the organization of the periodic table and explain its significance."
"Mendeleev is given the credit for advancing his idea more vigorously."
"J is the only letter that does not appear on the periodic table."
"The periodic table is valuable not because it's correct, but because it's useful."
"The beautifully coloured periodic table is because of lots of different groups, lots of different categories on the periodic table."
"This is the periodic table that we all know and love."
"The modern periodic table is arranged by atomic number."
"All elements in the same group have the same chemical properties because they have the same number of outer shell electrons."
"The periodic table is the world's greatest cheat sheet."
"We're the coolest elements on the periodic table."
"We can measure the entire periodic table from beryllium up to uranium and beyond in this one single analysis."
"There are no gaps in the periodic table now."
"We can also use ionization energies to work out what group of the periodic table a particular element might be in."
"This has got three outer energy level electrons which therefore means it is in group 3 of the periodic table."
"Mendeleev is generally given credit for discovering the periodic table because he had the courage to leave blank spaces in his table for elements that had not yet been discovered."
"It's kind of like the periodic table of elements; the deeper into chemistry you get, the more relevant that becomes."
"Understanding the periodic table and the relations between the elements that's based on physics."
"Even if quantum mechanics is mistaken in its description of the fundamental nature of the universe, we still expect the periodic table will be retained."
"The periodic table is quite remarkable; it contains essentially all of the information about the basic building blocks of everything on Earth."
"Which is the only group of the periodic table to include elements existing in the form of all three states of matter at standard pressure and temperature?"
"I read it off the periodic table, lyrically I got a myriad of fatal bars."
"The periodic table is still this amazing double thing. It's the basis of so much fundamental science; it's literally universal."
"Elements in a vertical column have similar chemical and physical properties."
"The modern periodic law was stated by a man called Dmitri Mendeleev."
"As you go across the period in the periodic table, ionization energy increases; as you go down the group, it decreases."
