Experiment #4. Elements and Compounds. Goals To practice naming and classifying elements and compounds Background Properties of Elements Elements on the periodic table can be classified as metals, non-metals or metalloids. The zigzag line on the table separates the metals from
Write the name and syol of each element described: the nonmetal in period 3 with the fewest protons the metalloid in group 17 (7A) the metal in period 3 with the most electrons the metal in group 2 with lowest atomic nuer the nonmetal in group 14 (4A) the
The metal or nonmetal is written first in the formula , followed by oxygen. 19. Methods:7 common-used nonmetal materials were burned in the coustion test box; and qualitative analysis was done by detective apparatus and GC-MS.
C. Write an “X” in the correct column to indie whether the element is a metal, nonmetal or metalloid. ELEMENT METAL NONMETAL METALLOID 1 aluminum 2 calcium 3 antimony 4 cesium 5 carbon 6 manganese 7 fluorine 8 silicon Worksheet 3-C D. Write
18/10/2007· Plutonium is none of the above. It is a "rare earth metal" or "rare earth element." Plutonium is from the "actinide series." It is part of "Group 3" and in the "7th period" on the Periodic Table. Plutonium is a radioactive, metallic chemical element. It has a syol Pu and
5.Which list of elements contains a metal, a metalloid, a nonmetal, and a noble gas? AAr BK CMg DSc 6.The chemical properties of calcium are most similar to the chemical properties of AArsenic has an atomic nuer of 33. BArsenic has a melting point of 84
This element has more valence electrons than oxygen, fewer valence electrons than neon, more protons than sodium, but fewer protons than argon.
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.
Classify the following element as metal, nonmetal, or metalloid: sodium A. metal B. nonmetal C. metalloid Question 2 Refer to a periodic table. The element calcium can be classified as A. an alkali metal

The Groups/Families of the Periodic Table •Elements on the periodic table can be grouped into families (or groups) based on their chemical properties. –We call them “families” because the elements in each family are “related.” •Each family has a specific name to
Diamond is not a metal in anyway its just an allotrope of carbon. It does not show any physical properties or chemical properties of metals like electrical conductivity, malleability, ductility,reaction with acids or salts etc. Carbon is actually a nonmetal, if you can believe the periodic table.
There are over 118 known elements in the world, and scientists are discovering new elements. Explore element examples to better understand what these tiny substances are. What Is an Element? An element in science, or specifically chemistry, can be defined as “any substance that cannot be separated into different substances by ordinary chemical methods.”

Boron - metalloid Calcium - metal Zinc - metal Hydrogen - nonmetal Neon - nonmetal Nickel - metal Sodium - metal Magnesium - metal Silver - metal Fluorine - nonmetal Silicon - metalloid Potassium - metal
Metalloids are considered all those type of elements which will not be considered only metal or nonmetal, therefore, the best definition is metalloid. They have a mixed property set which does not accounts for only one type of element. The most common types of
