What element is used everyday?
The roles of elements in your daily life are quite significant. For instance elements like oxygen and carbon dioxide are responsible for life itself. Other elements like nitrogen, aluminum and so on also have significant roles in our daily lives.
What is CH4 from the Periodic table of elements?
The periodic table of elements contains only elements, not compounds of these elements. CH4 is a compound made up of the elements carbon (C) and hydrogen (H), and is commonly known as methane, a gas that can be produced synthetically in a number of ways, and is also produced naturally by the decomposition of organic matter, and by the digestive systems of ruminants. Cows, for instance, release methane gas through flatus (farts).
Does Chlorine react to any other elements?
Yes, for instance, NaCl. Here, Chlorine, or rather the anion of Chlrone, Chloride, is reacting with Sodium's cation to form salt.
Can carbon react with chlorine?
Yes Carbon can react with several elements. Some acid strengths can be decreased with the addition of carbon with a bi product of hydrogen. Several other reactions with other elements can also happen. For instance, burning fossil fuel will release nitrogen water and other elements however, with carbon the water now becomes an acid, hence the term acid rain.
Which professions use et2 lightning elements?
There are many companies and professions which use ET2 Lighting elements. For instance, large business with lobbies may use ET2 Lighting. Movie theaters also use ET2 lighting. Electricians who specialize in installation of lighting will also use this type of lighting occasionally.
What did Dmitri Mendeleev find when he organized the elements by mass?
I believe the correct answer is he was able to predict the existence of yet undiscovered elements, due to the gaps. For instance, I believe germanium was one of the elements undiscovered in the table, its placeholder was called ekasilicon.
What would have happened if Dimitri Mendeleev did not create the periodic table of elements?
The table would almost certainly have been discovered/created eventually. The relationships between all the elements and their positions makes logical sense on so many levels that it would have happened eventually. The order would have been set in stone by the discovery of protons, for instance.
Why the relative atomic numbers of some elements are not shown in the periodic table?
All known elements are listed on the periodic table of the elements. Historical tables did not have elements listed that were unknown at the time. For instance, Dimitri Mendeleev, who laid out the first successful periodic table in 1869, did not have any of the noble gases listed since none of them had been discovered at that time. Modern periodic tables have gaps at the lower right end where elements are expected to be created in labs in the future, but have not been successfully created yet.
Is a rock organized?
No, although a rock could contain the remains of some organisms. Coal, for instance.
Is it possible for the amounts of some elements in earth's crust to decrease or increase?
Yes it would. For instance in the breakdown of radio-active elements.
Are there elements in solutions?
There can be elements or compounds in solution. For instance, sodium chloride is a solution of a compound. Conversely, a solution of bromine is a solution containing an element.
What is the weight of a mole?
It depends on the atomic mass. Carbon, for instance, is the standard for the mole. One mole of carbon is 12 grams. Other elements will be different. One mole of nickel, for instance, is 58.6934 grams. For other elements, simply look it up on the periodic table.
Static can be used in front of a constructor?
No. Static elements belong to the class, and the constructor belongs to the object (which is an instance of a class).
How does the elements of music create music?
You can sing about them like for instance "NO AIR" bu jordin sparks...-awesome person
Are elements different from other elements?
Yes, elements all have a different amount of protons in their atoms (number of protons = atomic number), but some elements have similar properties. For instance, the alkali metals all react in water, getting more violent as the atomic number gets higher.
What makes elements similar?
By elements being similar, I assume you mean elements of the same group being similar rather than all elements in general. Elements of the same group are similar in terms of chemical properties because they share a similar electron configuration. For instance group one of the periodic table, the alkali metals, has only one electron in its outermost unfilled orbital. Because chemical reactions are dependent on the exchange and sharing of electrons, the similarity of electron configuration in elements of a group results in them having similar properties. For instance, the alkali metals are all soft and extremely reactive.
How do you find valency of elements?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
