The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.
Me: I can name all the elements by proton number: hydrogen helium lithium beryllium boron carbon nitrogen oxygen fluorine neon sodium magnesium aluminum silicon phosphorus sulphur chlorine argon potassium calcium scandium titanium vanadium chromium manganese iron cobalt nickel copper zinc gallium germanium arsenic selenium bromine krypton rubidium strontium yttrium zirconium niobium molybdenum technetium ruthenium rhodium palladium silver cadmium indium tin antimony tellurium iodine xenon cesium barium lanthanum cerium praseodymium neodymium promethium samarium europium gadolinium terbium dysprosium holmium erbium thulium ytterbium lutetium hafnium tantalum tungsten rhenium osmium iridium platinum gold mercury thallium lead bismuth polonium astatine radon francium radium actinium thorium protactinium uranium neptunium plutonium americium curium berkelium californium einsteinium fermium mendelevium nobelium lawrencium rutherfordium dubnium seaborgium bohrium hassium meitnerium darmstadtium roentgenium copernicium nihonium flerovium moscovium livermorium tennessine oganesson.

one of the European plug and outlet standards that is widely used in continental Europe, excluding the UK and Ireland, and some other countries such as Morocco, Egypt, Ethiopia, Iran, Indonesia, China, and countries which formerly belonged to the USSR
A Type C plug (also called a Europlug) has two round pins. The pins are 4 to 4.8 mm wide with centers that are spaced 19 mm apart; the plug fits any socket that conforms to these dimensions. It also fits into Type E, F, J, K or N sockets that often replace the Type C socket.
