There is no chart. I’ll tell you a song that tells the elements in order.
There's Hydrogen and Helium Then Lithium, Beryllium Boron, Carbon everywhere Nitrogen all through the air With Oxygen so you can breathe And Fluorine for your pretty teeth Neon to light up the signs Sodium for salty times MAGNESIUM, Aluminum, Silicon, PHOSPHORUS Then Sulfur, Chlorine, and Argon POTASSIUM and Calcium so you'll grow strong SCANDIUM, Titanium, Vanadium and Chromium and MANGANESE This is the Periodic Table Noble Gas is stable Halogens and Alkali react aggressively Each period we'll see new outer shells While electrons are Added moving to the right Iron is the 26 then Cobalt Nickel coins you get Copper, Zinc, and Gallium Germanium and Arsenic Selenium and Bromine film While Krypton helps light up your room Rubidium and Strontium Then Yttrium, Zirconium NIOBIUM, Molybdenum, Technetium RUTHENIUM, Rhodium, Palladium SILVER-WARE then Cadmium and Indium TIN-CANS, Antimony then Tellurium and Iodine and Xenon and then Caesium and Barium is 56, and this Is where the table splits Where lanthanides have just begun Lanthanum, Cerium and Praseodymium Neodymium's next to Promethium then 62 Samarium, Europium Gadolinium, and Terbium Dysprosium, Holmium, Erbium Thulium, Ytterbium, Lutetium HAFNIUM, Tantalum, Tungsten Then we're on to RHENIUM, Osmium, and Iridium PLATINUM, Gold to make You rich 'till you grow old MERCURY to tell you When it's really cold THALLIUM and Lead then Bismuth for your tummy POLONIUM, Astatine would not be yummy RADON, Francium will last a little time RADIUM then Actinides at 89 This is the Periodic Table Noble Gas is stable Halogens and Alkali react aggressively Each period we'll see new outer shells While electrons are to the right Actinium, Thorium, Protactinium Uranium, Neptunium, Plutonium Americium, Curium Berkelium, Californium Einsteinium, Fermium, Mendelevium, Nobelium Lawrencium, Rutherfordium Dubnium, Seaborgium Bohrium, Hassium then Meinerium, Darmstadtium Roentgenium, Copernicium Ununtrium Flerovium Ununpentium Livermorium Ununseptium Ununoctium And then we're done
The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.
The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.
Now as the gametes fuse, both the n becomes 2n and diploid state is regained.
But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.
According to chemical evolution theory, life originated from inorganic molecules by the mode of chemical evolution. In primitive conditions of earth, only inorganic molecules were present. These molecules reacted under lightning, UV radiation and other environmental conditions to give rise to complex organic molecules like amino acids, sugars, lipids etc. They formed the basis for proteins, RNA and other molecules which ultimately led to the formation of cellular structures.
