The text explores different categories of chemical elements, including nonmetals, noble gases, alkali metals, alkaline earth metals, halogens, and metalloids. Nonmetals are characterized by their low melting and boiling points, brittleness, and are not typically found in a free state in nature.
A nonmetal is a chemical that lacks charter Physically a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid. and the nometals are hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon. Nonmetals used in crackers and in oxygen
Non Metals
A metalloid is a type of chemical element There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. There physical propeties are they are shiny, brittle solids with intermediate to relatively good electrical conductivity.
Mentalloid
A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile. There physical properties are high melting points.
good conductors of electricity. good conductors of heat. high density. malleable. ductile. Metals are very useful for humans cause we can make tones of thing with the like bridges, tools, buliding, and pipes.
Metals
The noble gases make up a class of chemical elements with similar properties; under standard conditions, there physical properties are a odorless, colorless, monotonic gases with very low chemical reactivity. the noble gasses are helium, neon, argon, krypton, xenon, and the radioactive radon. These are usually used for welding making lamps.
Noble Gases
The halogens are a group in the periodic table consisting of five chemically related elements: fluorine, chlorine, bromine, iodine, and astatine. The artificially created element 117, and they are found in row 17 of the periodic table.
Halogens
A Transition metal is an element whose atom has a partially filled d sub-shell. There physical properties are they are good conductors of heat and electricity. They can be bent into shape easily, and they have high melting points they are usually hard and tough, and thats why there used for maeking cars, tools and iron for steel.
Transition Metal
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium, magnesium, calcium, strontium, barium, and radium. The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
Alkaline Earth Metals
The alkali metals consist of the chemical elements lithium, sodium, potassium, rubidium, cesium, and francium. There physical properties are. High reactive metals. Not found freely in nature. Stored in a mineral oil solution. Low melting points.
