(b)
Interpretation:
To writethe electron configuration and the abbreviated electron configuration of Si Concept Introduction:The electron configuration is the distribution of electrons of an element in different orbits and orbitals.
(c)
Interpretation:
To calculate the
Concept Introduction:
(d)
Interpretation:
To write the balanced
Concept Introduction:A positron is a positively charged electron wherein the new element formed has the same mass number as the parent element but has -1 decreased atomic number.
Beta decay is the loss of an electron wherein the new element formed has the same mass number as the parent element but has +1 increased atomic number.
(e)
Interpretation:
Todraw the Lewis structure and predict the shape of SiCl4
Concept Introduction:Lewis structure shows the covalent bonds between atoms in a molecule. It also shows the lone pair of electrons on the element in the compound.
(f)
Interpretation:
To find how many hours are needed for a sample of Si-31 with an activity of 16µCi to decay to 2.0µ Ci
Concept Introduction:Radioactive decay equation:
where No is the initial activity, N(t) is the activity at time t, and t1/2is the half life of the radioactive substance.
