Atomic Science : Periodic TABLE

Kia ora this is what we have been learning in science

                                      WHAT DOES THE PERIODIC TALBE SHOW US

1. MASS NUMBER 
   The mass number, also called atomic mass number or nucleon number, is the total number of protons and neutrons in an atomic nucleus. It is approximately equal to the atomic mass of the atom expressed in atomic mass units

2. ElEMENTS
   each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e. the number of protons in the nuclei of its atoms.

3. ATOMIC
    A chemical element, also called an element, any substance that cannot be decomposed into simpler substances by ordinary chemical processes. ... Elements are the fundamental materials of which all matter is composed.
4. DIFFERENT COLUMNS
   A column is a vertical group of values within a table. It contains values from a single field in multiple rows. In databases, columns may be defined as individual fields within a table. ... Therefore, when multiple values from a column are selected, they will all have similar information, such as a list of phone numbers
5. DIFFERENT ROWS 
   When you lo0k at the pperiodic table, each row is callled a period (Get it? Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. Foor example, every element in the top row (the first periood) has one orbiital for its electrons.
6. FEATURES OF THE ELEMENTS  

• ALKALE METALS  

             Alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so-called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

•   TRANSITON METALS 

     Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one.

Elements: Gold; Copper; Iron; Platinum; Rhenium...

•  GLASSES 

       Periodic elements in glass

In addition to Si and O, the most important elements of silicate glasses are alkaline (Li, Na, K) and alkaline earth (Mg, Ca, Sr, Ba) metals, as well as elements Al and B.
