Understanding chemistry

Chemistry is the section of science that studies the characteristics of substances and their reactions when they are mixed with each other. Basically, chemistry is the study of matter and the composition, structure and reactions of matter. So what is matter? Everything on Earth and in our universe is made up of matter - anything you can see, touch or smell is considered matter.

Matter comes in three different main states: gases, liquids and solids. There's also a fourth state, plasma, but it only exists at very high temperatures. Molecules in a plasma state don't always behave the same. Speaking of molecules... atoms and molecules are what make matter possible. They're what every material in the universe is made of.

Confused? Because there are so many elements (a substance that cannot be broken down any further) and there's the chance of more being discovered, they've been organized into a table. The Periodic Table of Elements or Periodic Chart as it's also known as, is based on atomic numbers and electron configuration. There are 109 elements that make up the Periodic Table of Elements so far. Element names are abbreviated. Most of the time the abbreviations make sense (like C for Carbon) but not always (like Na for Sodium.) There are four elements that make up 99 percent of living organisms. They are: hydrogen (H), oxygen (O), nitrogen (N) and carbon (C).

The Periodic Table of Elements is arranged in rows called periods. Columns in the chart are grouped together by similar properties like gases, metals and earth. The number in each box is the number of atoms and the letters are the abbreviation for the symbol. Click here to check out the Period Table of Elements and more information on the elements.

Truly these are the end times I'm just going to post this and then not reply to you again because I already know how it would go.   You have given me two individual people in the first study, and five in the second. I'm not following how this is a consensus of anything. The HomeNet 1 study was inconclusive, it didn't exactly account for the people's different uses for Internet use. HomeNet 2 even validates my claim. They found that heavier internet use leads to a decline in face to face social interaction. But again, this test was before Internet networking became what it is today, along with every single study you have mentioned. I have found some good studies out there, but not anything that I wouldn't have to pay 30 bucks for or whatever. I never said that The Internet makes people lonely, I stated that the Internet is where lonely people go to find false solace. And that, is unhealthy. I'm just going to post this and then not reply to you again because I already know how it would go. OMG You're a psychic? What's my future?

People are not passively affected by technology, but actively shape its use and influence (Fischer 1992, Hughes & Hans 2001). The Internet has unique, even transformational qualities as a communication channel, including relative anonymity and the ability to easily link with others who have similar interests, values, and beliefs. Research has found that the relative anonymity aspect encourages self-expression, and the relative absence of physical and nonverbal interaction cues (e.g., attractiveness) facilitates the formation of relationships on other, deeper bases such as shared values and beliefs. At the same time, however, these “limited bandwidth” features of Internet communication also tend to leave a lot unsaid and unspecified, and open to inference and interpretation. Not surprisingly, then, one’s own desires and goals regarding the people with whom one interacts have been found to make a dramatic difference in the assumptions and attributions one makes within that informational void. Despite past media headlines to the contrary, the Internet does not make its users depressed or lonely, and it does not seem to be a threat to community life---quite the opposite, in fact. If anything, the Internet, mainly through #-####, has facilitated communication and thus close ties between family and friends, especially those too far away to visit in person on a regular basis. The Internet can be fertile territory for the information of new relationships as well, especially those based on shared values and interests as opposed to attractiveness and physical appearance as is the norm in the off-line world (see Hatfield & Sprecher 1986). And in any event, when these Internet-formed relationships get close enough (i.e., when sufficient trust has been established), people tend to bring them into their "real world"---that is, the traditional face-to-face and telephone interaction sphere. This means nearly all of the typical person's close friends will be in touch with them in "real life"---on the phone or in person--- and not so much over the Internet, which gives the lie to the media stereotype of the Internet as drawing people away from their "real-life" friends.
