From sugar to crystals, and hydrogen and oxygen to water, bonds are all around us, but how do they happen. How can you go from two dangerous chemicals such as sodium and chlorine and turn it into the table salt we eat every day?.
All elements contain atoms. The elements come together to form compounds that contain hundreds of atoms of different types. Atoms are made up of three smaller particles called protons, neutrons, and electrons. The protons and neutrons, which are neutral, are found in the nucleus of the atom. Protons have a single positive charge. Electrons have a single negative charge. Normally, atoms are electrically neutral so that the number of electrons is equal to the number of protons. Electrons orbit around the nucleus. In a bond the electrons get transferred between the elements/compounds. .
There are two main types of bonds, covalent and ionic. They are very different from one another.
Covalent Bonds are formed when two atoms share electrons. Covalent bonds usually form between two or more nonmetals. There are different types of covalent bonds such as polar and nonpolar. Polar bonds are covalent bonds where electrons are shared unequally. Nonpolar bonds are where the electrons are shared equally.
Ionic Bonds are attractions between negative and positive ions. Think of the two ends of a magnet. One is called the south end and the other is the north. When the two are put near each other they pull together because one has a plus charge and the other has a negative but when two plus sides or two negative sides are put near each other they push apart. Ionic bonds only form between metals and nonmetals. .
Atoms bond because they have either a positive or negative charge and they need to share them in order to make it a neutral atom. For example if you have an atom with a negative one charge and another that is positive one they bond together to form a compound that is neutral.

On June 16, 1995 the International Olympic Committee (IOC) announced the selection of Salt Lake City, Utah as the site for the 2002 Olympic Winter Games. ... It was reported that a shotgun and rifle were sent to the IOC president just one month before Salt Lake City was awarded the 2002 bid. ... The Salt Lake City organizers did not invent this culture. ... Federal spending will amount to around $1.4 billion on projects related to the 2002 Winter Olympic Games in Salt Lake City. ...

Salinity is known to reduce the growth of glycophytes (salt-sensitive species). ... Results Overall, Plants with little to no salt added to the soil experienced the most growth. ... Seeds with a lower concentration of salt experienced a larger stem, more leaves and more flowers. ... All of the data was compiled in the following table and graphs: % concentration % seeds germinated # of Flowers produced # leaves Stem Height 0 88 2.84 5.6 10.14 0.045 75 5 5.5 17.25 0.09 87.5 1.57 3.14 6.39 0.18 75 2.4 7.7 7.48 0.37 50 1 6 9.15 0.75 25 3.5 6 12 1.5 37.5 0 4 2.45 3 0 0 0 0 6 0 0 0 0 D...
Abstract The purpose of this project is to find out how table salt affects the boiling temperature of water. Our hypothesis is that when adding table salt to boiling water will cause the water to boil at a higher temperature. The materials we"ll be using to do this project will be: table salt, water, 2 quart cooking pot, pint measuring cup, teaspoon and tablespoon measuring spoons, thermometer, and a stirring spoon. ... Record the highest temperature reading. (3) Measure out table salt using a kitchen measuring spoon. (4) Add the measured salt to the boiling water and stir. (5) Measure the ...
Making Salt II. Introduction The purpose of the lab was to determine how many grams of sodium chloride (salt) are produced when sodium carbonate is reacted with hydrochloric acid. ... Continue this process until there is only salt left in the dish. ... Conclusion The purpose of this lab was to determine the amount of salt made when sodium carbonate is reacted with hydrochloric acid. ... Another thing that I noticed is when I was washing off the watch glass into the dish, I got a small amount of the washed off substance onto the table instead of in the dish. ...
It is the cause of when water tables raise due to sufficient rainfall in particular areas. ... A combination of water and salt build up in certain underground places, raises the water table and creates salt to rise to the surface. ... Now when it rains, the water is not absorbed by the trees and water tables rise allowing salt to come to the surface. ... This will help bring down the water table levels. ... These plants have been shown to effectively lower the water table and enable winter rainfall to leach surface salt to lower levels. ...
Salt is built up in Australia as a result of natural rock weathering, or the simple act of sea salt dropping via rain or wind and flowing into the water. Vast amounts of it has built up over thousands of years in the water table. ... Salt-affected soils occur when there are dramatic changes in the natural water systems whenever the land. ... Waterlogged salinity occurs when the water table is raised by excessive irrigation or rainfall. ... In an average year, 5.5 million tonnes of salt enter the sea via the Murray; 30 per cent of the salt is human induced. ...
Introduction The periodic table currently contains over 100 different elements that are known to this universe. ... They dipped the stick in salt of the element and put that on the flame. The flame of fire changed colors from yellow, red, blue and many other colors depending on the type of salt used. ...
