Problem: Article: Experiment with new activities that might interest you. When you stretch your comfort zone, you get yourself out of a rut. You inject more excitement into your life. You meet new people. Be open to trying new activities so that you learn to be a little more fearless. Try volunteering at a nonprofit organization, or learning a new sport or hobby. Pick something that you have very little experience with and go for it! Your goal to become more interesting might involve becoming more courageous or being friendlier. But it's difficult to achieve these traits unless you have a specific plan in place. Try out concrete activities or skills, instead of focusing on building one of your personality traits. For example, instead of convincing yourself you need to be more courageous, you might try simply participating in an activity that produces some degree of fear when you think about it. Or, you could try rock climbing if you are afraid of heights, or visit a petting zoo if you are afraid of animals. By pushing yourself out of your comfort zone, you might eventually become more comfortable with participating in activities you or others might find interesting. When you expand your network of acquaintances, you can become exposed to more interesting situations and activities. Ask people questions about themselves. Once you get someone talking, you may discover, for example, that this person has expert knowledge of beekeeping, an activity you've always wanted to try. Seeing more of the world can make you more attuned to subtle differences between people from different backgrounds or different ethnicities.  Being sensitive to how these differences affect others and yourself can sometimes make people feel more comfortable around you.  This will also give you a greater sense of what interests you can look like in different parts of the world. Make your next holiday an unusual one. Go to an exotic place and do things you would not normally do. This might include an activity such as backpacking, surfing, climbing a mountain or going on a jungle safari. Read books about fun topics such as how to make unique cocktails, exotic places to travel or how to become a great lover. These topics will give you lots of material for riveting conversations.
Summary: Try out new activities to stretch your comfort zone. Build your personality traits by trying out concrete activities. Meet new people. Travel as much as possible. Read more.

Problem: Article: In naming compounds, Greek prefixes are used to indicate the number of atoms present for each element. Covalent compounds are written out as molecular formulas due to the fact that each compound is a distinct, separate molecule. Covalent compounds have the first element written out completely while the second element is named with the suffix “ide.” For example, diphosphorus trisulfide has a chemical formula of P2S3. Below are the prefixes for 1-10:  1: Mono- 2: Di- 3: Tri- 4: Tetra- 5: Penta- 6: Hexa- 7: Hepta- 8: Octa- 9: Nona- 10: Deca- When a compound has been written out, you must identify the elements and know their chemical symbols. The first element written is “first name” of the compound. Use the periodic table to find the chemical symbol for the element. For example: Dinitrogen hexafluoride. The first element is nitrogen and the chemical symbol for nitrogen is N. To identify the number of atoms present for each element, you simply need to look at the prefix of the element. Memorizing the Greek prefixes will help you to be able to write chemical formulas quickly without looking anything up.  For example: Dinitrogen has a the prefix “di-“ which means 2; therefore, there are 2 atoms of nitrogen present. Write dinitrogen as N2. The second element is the “last name” of the compound and will follow the first element. For covalent compounds, the element name will have a suffix of “-ide” instead of the normal ending of the element. For example: Dinitrogen hexafluoride. The second element is fluorine. Simply replace the “ide” ending with the actual element name. The chemical symbol for fluorine is F. As you did with the first element, identify the number of atoms present in the second element by reading the prefix. Using this prefix, write the number of atoms as a subscript to the right of the chemical symbol.  For example: Hexafluoride has a prefix of “hexa-“ which means 6; therefore, there are 6 atoms of fluorine present. Write hexafluoride as F6. The final chemical formula for dinitrogen hexafluoride is N2F6. When first learning chemistry, there is a lot of memorization involved. It is kind of like learning a new language. The more examples you practice with, the easier it will be to decipher chemical formulas in the future and learn the language of chemistry.  Sulfur dioxide: SO2  Carbon tetrabromide: CBr4  Diphosphorus pentoxide: P2O5
Summary:
Memorize the prefixes for number of atoms. Write the chemical symbol for the first element. Add the number of atoms as a subscript. Write the chemical symbol for the second element. Add the number of atoms present as a subscript. Practice with some examples.
