Given current=16A
the charge on electron=1.6*10^-19C
Let n electrons strike per unit time
n*1.6*10^-19=16
n=10^20 electrons/s
=1.00*10^20 electrons/s

Review Constants 1 Periodic Table Part A en, beryllium, and boron are examples of s that can have less than an octet of is in a covalent compound. Even without an ydrogen achieves the helium configuration, refore noble-gas stability, by forming one nt bond. Beryllium and boron simply do not nough electrons to form the number of bonds to achieve an octet. Instead, Be uses its lence electrons to form two bonds, and B s three valence electrons to form...
