Why is the periodic table called the key of life?
It is called the key of life because all the elements or compounds of the elements of on the periodic table make up the world.
What is the charge on lead with 78 electrons?
+4 On the periodic table, all elements are neutral. And that is the key to this problem. Lead (Pb) on the periodic table has an atomic number of 82. Therefore it has 82 protons. How many electrons would it need to be a neutral atom then? Obviously, 82! So if we have 82 electors and 82 protons we have neutral lead, but we don't have 82 electrons we only have 78. Therefore neutral lead lost negatively charged electrons. When you lose a negative you become more positive. So we have a charge of +4, since 82-78=4. In general the solution to this problem is: (Atomic Number) - (Number of Electrons) = (Net Charge)
What are the application and theories in different branches science?
The periodic table of the elements forms the basis of chemistry, the prevailing theory is that each element is primarily distinguished from another by the number of protons in its atomic nucleus. The primary theory of cosmology is the "big bang" theory. This is not a particularly good name, because it evokes the idea of an explosion, which is not really how it occurred. Astronomy consists of both the big bang and Subrahamanyan Chandrasekhar's theory of stellar evolution. The primary theory of geology is plate tectonics. For biology the key concept is Charles Darwin's theory of evolution. Isaac Newton's method of fluxions (theory of calculus) is probably the key concept in mathematics, much as Euclid's Elements form the basis of geometry.
What is The science of classification is called?
Type your answer here... Systematique ...in french. In fact Taxonomy is more oriented on descriptive and classification aspects as systématique focuses on inter-relations and how taxons are organized in evolution
What do you call a systematic scientific documented study?
Science? I think im working on the same L. Farrell crossword as you. Anyways, It fills it in, and 53 accross is electrolyte. (ps. there's no key, welcome to hell)
Why is the periodic table called the key of life?
It is called the key of life because all the elements or compounds of the elements of on the periodic table make up the world.
How is metallic character shown on the periodic table?
The metallic elements on a periodic table may be represented by a certain color unlike those of other elements. Most periodic tables have elements in different colors, so try looking at the key that shows what each color represents for that element.
How do you work out the number of valence electrons in a substance?
Just get to know the periodic table of the elements; that is the key to understanding valence electrons.
The most useful source of chemical information about the elements is a?
periodic table. The periodic table provides a concise and organized overview of all the known elements, including their atomic number, atomic mass, and other key properties. It allows scientists to quickly access information about each element, such as its electron configuration, valence electrons, and chemical reactivity.

Why do the key features of the periodic table relate to the results of titration?
You don't need the periodic table for titrations (manual or potentiometric).
What are some key features about the organization of the periodic table?
63526786
Which pure substances does the periodic table provide information about?
The Periodic Table provides a surprising amount of Information about all of The Atomic Elements in their mono-Atomic form.It is "also" the Key to The Code that determines which Atom will, may, or can Covalently Bond with which Other Atom and specifically especially in which Configurations.
What is asterisk and what does it have to do with the periodic table of elements?
That is this symbol: * It is used to mark printed or written text, typically as a reference to an annotation or to stand for omitted matter. Your table should have some sort of key to indicate what this refers/ pertains to.
How does a new element get put on the periodic table?
The key defining characteristic between elements is the number of protons their atoms have. The periodic table is organized by increasing atomic numbers which are the number of protons each atom has. So a new element would be given an atomic number equal to the number of protons it has, then placed wherever it lands in numerical order with the all the existing elements.
How can you tell which elements are metals and non metals?
Most elements on the table are metals. However, the nonmetals are located on the right side of the table. You need to start with a color-coded periodic table; this will show you metals,nonmetals, and metalloids.
Out the elements F B O and N which is the most active?
Fluorine (F). It has the highest electron affinity which essentially means it is the most willing to gain an electron. Fluorine is also the MOST reactive element on the periodic table. Key to remember, as you go from left to right across the periodic table, the activity increases. As you go from top to bottom the activity decreases.
