PH is the amount of hydrogen ion concentration in a sample. Basic because a ph of 0-7 is acidic and 7-14 is basic
The properties of aluminium include low density<span> and therefore <u><em>low </em></u></span><u><em>weight</em></u>, <u><em>high strength</em></u>, <u><em>superior malleability</em></u>, <u><em>easy machining</em></u>, <u><em>excellent corrosion resistance</em></u> and <u><em>good thermal and electrical conductivity</em></u><span> are amongst aluminium's most important properties. <u><em>Aluminium is also very easy to recycle.</em></u>
Hope this helps:D

Periodic trends , arising due to the arrangement of the different elements in a periodic table. It includes electronegativity, ionization energy,electron affinity, atomic radius, metallic character and chemical reactivity.
With the help of the periodic trends,we can predict or determine an element's properties.
