The syol N belongs to the nitrogen element which belongs to period 2 and group 5A / 15 from the periodic table. It is the main group element as all element in the group named as A is the main group element. Its atomic nuer is 7 and atomic mass is 14.01 u …
In Groups 4A-6A, there are several elements whose syols begin with S. Name these elements, and for each one give its syol, atomic nuer, group nuer, and period. Describe each as a metal, metalloid, or nonmetal.
Use the element syol to loe an element in the periodic table. Count down the rows of elements to determine the period. The group nuer is loed at the top of each column. Element Period Group a. Oxygen 2 6A (or 16) b. Calcium 4 2A (or 2) c. Phosphorus
Directions: Use your periodic table to find the Syol, atomic nuer & atomic mass (round the atomic mass to the nearest whole nuer). Determine if the element is a metal, nonmetal or metalloid and if it is a solid, liquid or a gas at room temperature. 1.

30/6/2009· I. Classify each of the following elements as a metal, nonmetal, or metalloid. 1. Na 2. Ge 3. Si 4. Br 5. Ag II. Determine the charge of each of the following ions. 1. tungsten ion with 68 electrons 2. tellurium ion with 54 electrons 3. nitrogen ion with 10 electrons 4. barium ion with 54 electrons III. Determine the nuer of protons and electrons in each of the following. a) Al 3+ b) S 2- c
Elemental calcium is indeed a metal, although a reactive one that tends to oxidize in air because of reaction with oxygen. The Ca 0 metal is not found often in nature for this reason. The "calcium" we talk about when we think of calcium scale on pluing is calcium carbonate , and other calcium salts.
