The table is organized into rows, called periods and columns, called groups . The atomic number of an element is the number of protons in each of the atom of the element. The elements in the periodic table are in order by increasing from left to right across each period.

Because it only has 1 valance electron, but it is considered as non metal.
Propwerties from hydrtogen are very different of ther akali metals.]]> 2017-10-10 18:46:48 UTC https://padlet.com/ichaves/guopv8gosyce/wish/195774358 dmora4 https://padlet.com/ichaves/guopv8gosyce/wish/195774453  The valance electrons of an atom are those electrons that have higest energy.]]> 2017-10-10 18:47:00 UTC https://padlet.com/ichaves/guopv8gosyce/wish/195774453 dmora4 https://padlet.com/ichaves/guopv8gosyce/wish/196970908  The number of valance electrons is specific to that element. Different elements can have have from 1 to 8 valance electrons]]> 2017-10-13 20:43:13 UTC https://padlet.com/ichaves/guopv8gosyce/wish/196970908 dmora4 https://padlet.com/ichaves/guopv8gosyce/wish/199698695  Atoms tend to be more stable if they have 8 valance electrons.
A chemical bond is the force of atracttion that holds together as a result of the rearrengment if electrons between them]]> 2017-10-23 17:30:22 UTC https://padlet.com/ichaves/guopv8gosyce/wish/199698695
