The building block of silicate minerals is called silicon - oxygen tetrahedron (this is the option A)<span>. This silicate ion is Si O4 (4-); it consists of one atom of Si, located in the center of a tetrahedron and surrounded by 4 atoms of O, located in the vertices of the tetrahedron. Given that the SiO4 (4-) ions have a negative charge of 4, they will bond to four metallic cations, each with 1 positive charge.</span>

After 11.5 days, 12.5% of a sample of radon-222 that originally weighed 42g remains. What is the half-life of this isotope?
Bond [772]
Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value.  The equation to describe the decay is
Nt=N0(1/2) ^{t/t(1/2)}  where N0 is the initial quantity, Nt is the remaining quantity after time t, t1/2 is the half-time.  So work out the equation, t1/2 = t (-ln2)/ln(Nt/N0) = 11.5*(-ln2)/ln(12.5/100) = 3.83 days

absorbed when the bonds are broken.

<h3>What is a chemical reaction?</h3>

A chemical reaction involves the formation of new compounds from

reactants . It involves the formation and breaking of bonds in the
