Metals vs. Non-Metals; Dot Diagrams; Ions Metals versus Non-Metals Dot Diagrams Metals are on the left side. Non-metals on the right. Metals tend to lose electrons. Non-metals gain them tight. Dot Diagrams (sometimes known as Lewis dot diagrams) are a depiction of an atom’s valence elect

Metals and Non-metals CHAPTER3 In Class IX you have learnt about various elements.You have seen that elements can be classified as metals or non-metals on the basis of their properties. n Think of some uses of metals and non-metals in your daily life. n What properties did you think of while categorising elements a

For example, metals can react with many non-metals: e.g. calcium chlorine calcium chloride (Note: When naming a compound the ending of the non-metal is changed to ide) Metals can also react with air (oxygen), water and acids. Some metals

Metals Metals make up the largest class of chemical elements in the Periodic Table. Approximately three quarters of elements are metals. Most metals are silvery in colour, have a characteristic lustre, and are solid (rather than liquid or gaseous). Most metals are also

The alkali metals are very reactive The Alkali metals easily lose one electron. They form 1 ions in ionic compounds. The alkali metals even react violently with water to make H 2 gas and [OH]- ions. The [OH]- are a base and this is where the alkali metals get there name from, as alkali means

Metals also tend to be solid (not an absolute) in natural form. nonmetal – An element that lacks the physical and chemical properties of metals. That is, the element is not shiny, not a good conductor, and is not malleable or ductile.

metals. Solid nonmetals are dull, meaning not shiny, and brit-tle, meaning not malleable or ductile. If you hit most solid non-metals with a hammer, they break or crumble into a powder. Nonmetals usually have lower densities than metals. And non-metals are also poor conductors of heat and electricity. FI

Chemistry 51 Chapter 5 4 IONIC COMPOUNDS Ionic compounds contain ionic bonds, which occur when electrons are transferred between two atoms. Ionic bonds occur between metals and non-metals.

properties. The most reactive metals are the alkali metals in Group 1 on the far left side of the periodic table. The Group 2 elements are the alkaline earth metals, which are somewhat less reactive than the alkali metals. Groups of elements become less metallic in their properties from left to right across the periodic table.

Metals readily combine with nonmetals to form compounds but rarely combine with other metals. Some metals are found in their free states, like copper, gold and silver. Some metals are mixed to form homogeneous mixtures called alloys: brass, bronze, steel and
