The periodic table of elements is divided into columns and rows. The vertical columns represent the groups while the horizontal rows represent the periods. A group of elements usually have similar physical and chemical properties. The first column of the periodic table is made up of 7 elements including SODIUM.
1. The name of the element chosen is sodium and its chemical symbol is Na.
2. Sodium is a metal and thus it has metallic properties.
3. Sodium belongs to group one elements whose family name is ALKALI METALS.
4. The neutral atom of sodium is made up of 11 protons, 11 electrons and 12 neutrons.
<span>In a mole of anything, there are 6.023 x 10^23 units. So, in 3.9 moles of sulfur, there are 3.9 * 6.023 x 10^23 = 23 x 10^23 = 2.3 x 10^24 atoms (keeping only 2 sig figs). Hope I help!!
