<em>The correct option is G) Mercury has 51 more electrons than copper.</em>

The atomic number of mercury is 80. This means that an atom of mercury has 80 electrons.

Th atomic number of copper of copper is 29 which means that copper has 29 electrons.

80 - 29= 51

Hence, mercury has 51 more electrons than copper.

Does anyone know what Complete sentence response mean?
Umnica [9.8K]

Answer:

The aim in writing is always to write in complete sentences which are correctly punctuated. Sentences always begin with a capital letter and end in either a full stop, exclamation or question mark. A complete sentence always contains a verb, expresses a complete idea and makes sense standing alone. A complex sentence is a sentence that contains an independent clause and one or more dependent clauses. An independent clause can stand alone as a sentence, but a dependent clause even though it has a subject and a verb cannot stand alone. Here are some examples of complex sentences.
