Which Group On The Periodic Table Is Highly Reactive In Water? The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table – they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen. Which elements are highly reactive water? Water reactive
Who Used Patterns To Predict Undiscovered Elements? Mendeleev went even further. He corrected the known atomic masses of some elements and he used the patterns in his table to predict the properties of the elements he thought must exist but had yet to be discovered. He left blank spaces in his chart as placeholders to
Who Was The Author Of The Book The Elements? The Elements (Ancient Greek: Στοιχεῖον Stoikheîon) is a mathematical treatise consisting of 13 books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt c. 300 BC.

Which Period Has Only Gases? A period 1 element is an element in the first period (row) of the periodic table. … It means that elements in the same group have similar properties. The first period has less elements than any other periods in the periodic table. There are only two elements in the first
Which Properties Are Characteristic Of The Group 2 Metals? Being a metal, they are obviously good conductors of heat and electricity. The general electronic configuration of Group 2 elements is ns2. Alkali earth metals have the capability to lose the two electrons in their outer shell. Which properties are characteristics of Group 2 elements? Although
Why Does Group 7A Have A 1 Charge? The Group 7A elements have seven valence electrons in their highest-energy orbitals (ns2np5). This is one electron away from having a full octet of eight electrons, so these elements tend to form anions having -1 charges, known as halides: fluoride, F–; chloride, Cl–, bromide, Br–, and iodide,

What Is An Element Of Maya Culture? The Zapotecs were clearly influenced by (or, perhaps, related to) the Olmecs and, through them, some of the most important cultural elements of the region were disseminated such as writing, mathematics, astronomy and the development of the calendar; all of which the Maya would refine. What are the
Who Created The First Periodic Table? British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. Who created the original periodic table? British chemist John Newlands was the
