An atom has a charge of +1 in its nucleus. which statement must be true in order for this atom to have no net charge? a. the one positive proton has no influence on the overall charge of the atom. b. there is one negatively charged electron outside the nucleus. c. there is one neutral neutron in the nucleus as well. d. there is one negatively charged electron in the nucleus.

the answer is false because not all countries have geysers under their crust. for example, iceland uses geothermal energy because it is available every in their country.  

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
