Answer:
Sodium
Explanation:
Sodium in period 3 has three electron shells. Recall that the period to which an element belongs shows the number of electron shells present in each atom of the element.
Beryllium is in period two, hence it possesses only two electron shells. However, beryllium is a member of group two hence it has two valence electrons in its outermost shell.
Sodium on the other hand has only one electron in its outermost shell since it is a member of group one. Hence the element must be sodium.
Answer:
Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate. ... Most electric charge is carried by the electrons and protons within an atom.
Explanation:
because it is
Charge on a capacitor = (capacitance) x (voltage)
7.68 Coulomb = (capacitance) x (9.0 V)
Capacitance = (7.68 Coul) / (9.0 V)
<em>Capacitance = 0.83 Farad</em>
<em></em>
Apparently, the " 10^something " after the 7.68 C got lost.
If the charge is actually 7.68 <u>micro</u>coulombs, then the answer is<em> (A) .</em>
