info giver with periodic table By:Brice holliday

Metal-they are in jewelry and also it is in pots and pans their also use as electrical current non-metals is an element that do not contain metal and the properties of nonmetal is cement, glass,and all of these elements have hydrogen. metalloids-is in the area that is red on the top picture above this text also the properties of the metalloids is boron, and also silicon.
protons and neutrons are in the center (nucleus) of the atom. ... Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.
Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He formulated the Periodic Law, created a farsighted version of the periodic table of elements, and he show what elements are more reactive and least reactive.
as you see the picture the reactivity of the elements get more stronger as the arrows you to look or to go
In the periodic table of the elements, each numbered column is a group. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table, but the f-block columns (between groups 2 and 3) are not numbered.
When you look at the periodic table, the symbols and numbers look like the image on the left. The symbols are abbreviations of the origins of the word for each element. For example, the origin of lead's symbol, Pb, is the Latin word 'plumbum' meaning 'liquid silver'. The number above the symbol is the atomic mass (or atomic weight). This is the total number of protons and neutrons in an atom. The number below the symbol is the atomic number and this reflects the number of protons in the nucleus of each element's atom. Every element has a unique atomic number. Lead has 82 protons therefore its atomic number is 82. The elements are then arranged in order of increasing atomic numbers - so hydrogen (H), which only has one proton, is located first in the table, while sodium (Na), which has 11 protons, and is found further down the table. We can use atomic number and atomic mass to find out the number of protons, neutrons and electrons there are in an atom. By subtracting the atomic number from the atomic mass we can discover the number of neutrons there are.
In general, to balance an equation, here are the things we need to do: Count the atoms of each element in the reactants and the products. Use coefficients; place them in front of the compounds as needed.
Physical and Chemical Properties All substances have properties that we can use to identify them. For example we can idenify a person by their face, their voice, height, finger prints, DNA etc.. The more of these properties that we can identify, the better we know the person. In a similar way matter has properties - and there are many of them. There are two basic types of properties that we can associate with matter. These properties are called Physical properties and Chemical properties: Physical properties: Properties that do not change the chemical nature of matter Chemical properties: Properties that do change tha chemical nature of matter Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples. Note that measuring each of these properties will not alter the basic nature of the substance. Examples of chemical properties are: heat of combustion, reactivity with water, PH, and electromotive force. The more properties we can identify for a substance, the better we know the nature of that substance. These properties can then help us model the substance and thus understand how this substance will behave under various conditions. Back
Atoms are building blocks. If you want to create a language, you'll need an alphabet. If you want to build molecules, you will need atoms of different elements. Elements are the alphabet in the language of molecules. Each element is a little bit different from the rest. Why are we talking about elements when this is the section on atoms? Atoms are the general term used to describe pieces of matter. You have billions of billions of atoms in your body. However, you may only find about 40 elements. You will find billions of hydrogen (H) atoms, billions of oxygen (O) atoms, and a bunch of others. All of the atoms are made of the same basic pieces, but they are organized in different ways to make unique elements. Common Elements
