Using the periodic table, complete the following. Element: iron
symbol: Fe
Atomic weight:
g
Mass of one mole:
g/mol

Answer in explanation

Explanation:

We are to use a standard periodic table to answer this question

According to a periodic table;

The atomic weight of iron is 55.845 atomic mass unit

The mass of one mole of iron is same 55.845 g/mol

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.
