Draw Lewis structures for the molecules below. Draw resonance structures where appropriate and label any formal charges. Calculate the bond orders. 1) [SCN]- 2) [HC2O4]- 3) SNF3 4) [S2CO]2- 5) [IO3]- 6) [SO4]2- 7) [S3N3]- (cyclic, every other atom is S) 8) [ClO4]- 9) [NO2]- 10) N2O 11) [ClO4]-

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

the answer is c i believe

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
