what is preiodic table
Answers
Answer:
a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
Answer :
The Periodic Table :
There are over 100 different elements, each with different properties, The Periodic Table displays all elements in the order of their atomic numbers. The table has several rows called periods arranged on top of each other. As a result, elements with similar properties are arranged in vertical columns called groups. The zig-zag line at the right-hand side of the periodic table divides the metal and non-metals.
Atomic Number :
The protons in an atom are called its atomic number. Each element has a different atomic number. Elements contain neutral atoms. Since protons are positively charged particles, there must be an equal number of negatively charged electrons. So, the atomic number tells us how many electrons the atom has.
