The Periodic Table is arranged in order of increasing atomic number (the number of protons in one atom of an element). The reason the table cuts of at group 8 (the noble gasses) is because each group has a set of characteristics that are repeated. These characteristics are directly related to the number of electrons in an atom's outer shell. Group 8 has a full outer shell of 8 electrons, so this is where the table begins again at group 1.
The Periodic table of elements was created by a Russian scientist named Dmitry Ivanovich Mendeleev. When he created it in 1869 not a lot of elements had been discovered. He put the table together using the elements atomic number. Hydrogen for example is first on the periodic table because it's atomic number is one. When he completed it there were a lot of gaps. What Dmitry did was he actually predicted the existence of other elements where the gaps were on the periodic table. A lot of the elements have been found but a few are still 'unobserved'. The periodic table is set out using it's atomic number. There is also the AMU which is the atomic mass unit but it does not have much to do with the set out of the periodic table.
figure it out your selves!! its got to be in a book somewhere... but i have no clue so you tell me... please?
No. No change at the atomic level. An atom is just an atom. Atoms together make molecules. Molecules is where structure arrives and together make organisms.
Diamond is simply Carbon (C). The same element that graphite in pencils is made of. Diamonds are highly unreactive.The principle element in diamond is carbon. What gives diamond its hardness and rarity is the way in which the carbon atoms are held together and bonded.Brief description: carbon is a Group 14 element and is distributed very widely in nature. It is found in abundance in the sun, stars, comets, and atmospheres of most planets.Carbon is found free in nature in allotropic forms: amorphous, graphite, and diamond.Graphite is one of the softest known materials while diamond is one of the hardest.Carbon, as microscopic diamonds, is found in some meteorites.Natural diamonds are found in ancient volcanic "pipes" such as found in South Africa.Diamonds are also recovered from the ocean floor off the Cape of Good Hope.yes it is composed of carboncarbon carbon carbon Diamonds are 100% pure carbon, with the atoms arranged in crystal lattice
Molecules Atoms which are elements make up molecules. Protons and electrons make up atoms.
No. Atoms are the smallest units of matter, and cells are made up of atoms grouped in molecules (which are collections of atoms). Think about it like this: Atoms are the basic building blocks of all matter, but cells are the basic building blocks of life. Also cells have directives, and they also make up life. Atoms make up cells which make up life.
what 3 things make the structure of a DNA molecule
An atom and an element are synonyms. Rather, subatomic particles make up atoms (and elements). The three types of subatomic particles are neutrons, protons, and electrons.
One you idiot it's an element Au
No, structure is not an element. That would make no sense...
they are alike because they all have mass ther diffrent because there lines, and isotpes
1 atom make up the element carbon.It has atomic number 6.
Atoms are the components that make up the Elements.
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms
No. No change at the atomic level. An atom is just an atom. Atoms together make molecules. Molecules is where structure arrives and together make organisms.
CuSO4 isn't an element.
yes its true because its an element and if you want to make an element you will have to have one sort/type of atoms together (neon has 10 atoms to make an element) .
Atoms and molecules
It takes two atoms to substanciate the atomic substance. ie. One atom does not equal the element. Molecules, on the other hand, are made up of numerous atoms depending on their atomic structure. Be warned: I am not a physicist or a chemist.
