03.04 Valence Electrons and Bonding Individual neutral atoms are rarely found in nature. The noble gases are the only elements that are found as single atoms more often than they are found in compounds. Atoms are held together in compounds by electrostatic attraction between positive nuclei and negative electrons. This attraction holds atoms together in a chemical bond‚ a link between two atoms resulting from the mutual attraction of their nuclei for valence electrons. All chemical bonds involve

of Language Light can take on many different forms‚ some more prominent than others. This concept is explored through the poem‚ “The Grammar of Light”‚ written by Carol Ann Duffy. The title itself is a metaphor as the term ‘light’ is being compared to language and how it can be structured in several different ways. As grammar is the study of how language is structured‚ Carol Ann Duffy uses the structure of light to emphasize language’s potential and/or its limitations. Because light is shown through

positive charges in the neutron and the electrons. Due to the increase of the number of positive charges‚ the electron’s attractive force becomes stronger‚ thus (the electrons) being drawn close to the nucleus. The stronger the attractions causes the electrons move closer to the nucleus‚ decreasing the size. When going down the column (group)‚ the number of electron shells that are occupied increases‚ creating a shield. The shield are the inner shells that have electrons making the outermost level being

* Biology Investigation 3.1 Porcellio Scaber (Slater‚ Woodlouse) Task 1 The crustacean Porcellio Scaber‚ or more commonly known as the woodlouse‚ is a species usually found in leaf litter or in fallen trees and bark. It feeds on detritus like many other isopods of its type‚ and is generally predated on by small mammals‚ lizards and some insects. The woodlouse habitat reflects its need to avoid warm and dry areas. The woodlouse is prone to desiccation (drying out) due to its body’s large surface

one and all. Education is the light of our life It is the key to a bright future Of not only ours but also of the nation’s It gives our thinking a different appearance And helps drive away all our ignorance It leads us to the path of the success Knowing the significance of it without education‚ we realize we are somewhere incomplete. Without education people can be easily cheated‚ be-fooled & deceived. Education is the movement from darkness to light. Many people in our country

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability

Urban Transport in Indian Cities A peak of rush hour commuters at Churchgate‚ a terminus for one of Mumbai’s main suburban train lines contributing to the nearly 6.5 million people feeding in and out of the city daily. Urban travel in Indian cities predominantly happens through walking‚ cycling and public transport‚ including intermediate public transport (IPT). Despite high growth rates of motorised two wheelers and cars in the last two decades (15 per cent and 10 per cent per annum respectively)

too dependent on technology. Nowadays people are way too dependent on technology. Most people use technology for everything. They would be lost without the internet and wouldn’t know what to do. People are becoming lazy as most things are being replaced with new and improved technology. This technology is usually the most efficient way to do certain things and soon we will all be dependent on it. Imagine what it will come to in the future as our world of technology expands. People are using technology

Physical Light and Spiritual Light In this discussion‚ there are two kinds of light that are going to be compared. The two kinds of lights that are going to be compared against each other in this discussion are going to be; physical light and spiritual light. As we all know‚ the sun‚ stars‚ oil lamps will all eventually burn out‚ whereas the light of God is forever‚ so showing that spiritual light‚ God’s light‚ is much better than physical light. In Genesis 1:3 God said let there be light and there
