Atoms that have the same number of outer electrons
A.
are all metallic elements.
B.
belong to the same family of elements.
C.
are all nonmetallic elements.
D.
must be atoms of the same element.
1. Atoms that have the same number of valence electrons in their outer shell have similar properties and belong to the same family of elements. Valence electrons are the outermost electrons in the atom and are important in determining how the atom chemically reacts with other atoms.

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
