Problem: Article: You'll find this phone-shaped app icon on the Home Screen, or you can swipe up or down to open the App Drawer and look for it there. It's in the top-right corner of the screen. Tapping it prompts a drop-down menu. This is in the drop-down menu. Doing so opens the Call Settings page. It's in the "CALL SETTINGS" section of the page. The switch will change color, signifying that your Samsung Galaxy will no longer take calls from unknown sources. If you just want to block a single number, type it into the "Add phone number" text box near the top of the page and then tap Done in the keypad. You'll still be able to receive calls from people who aren't in your contacts as long as they're using actual phone numbers. If you want to restrict incoming calls to only people who are in your contacts, try using the "Should I Answer?" app.
Summary: Open the Phone app. Tap . Tap Settings. Tap Block numbers. Tap the white "Block anonymous calls" switch .

Problem: Article: Keep the fish flat on the surface, but grab hold of the tail so it won't slip around when you start removing scales. You may want to put on a pair of disposable gloves to protect your hands. Scales and fins can be sharp. To remove scales, use the blunt edge of the knife instead of the sharp edge. Hold the blunt edge at a 45 degree angle. Place the blunt edge right up against the fish's skin near it's tail fin. Rake the backside of the knife along the side of the fish, moving from its tail to its head. Make long, even strokes. You'll need to apply a little pressure, but not much. As you scrape, the scales will start popping off. It's going to get a bit messy! Continue until that side of the fish has no remaining scales. Flip the fish over and repeat on the other side. After you have removed all the scales you can with the knife, hold the fish under cold running water. The water should help get rid of any scales that are still on the fish. Keep rinsing until no scales remain.
Summary: Hold the fish firmly by the tail in your non-dominant hand. Take a knife in your dominant hand and turn it to the blunt edge. Scrape the side of the fish from the tail to the head. Rinse away any remaining scales with cold water.

Problem: Article: Feel free to express your true opinions and personality. If your suitor sticks around, your company was found truly enjoyable. If another date doesn't come about, you may feel rejected, but this proves that you were just not meant to be. Being honest and being true to yourself can help you avoid wasting time while dating. Furthermore, acting the way you think your suitor wants you to act rather than being yourself can foster feelings of resentment, stress, and discomfort. These feelings do not set a solid foundation for a relationship. You might find someone there who shares the interests and more! This event and the commonalities you have will create easy talking points, and might lead to a first date. If you love literature and art, join a book club or get active in the artistic community. If you love to cook, take a cooking class and whip up conversation with a fellow chef. Even if you don't connect with anyone, you're still doing something you love. Your suitor may not fit the ideal picture you had in mind, but if it feels right, pay attention to that. On the contrary, if there's anything that is disturbing to you, don't ignore the signs. Your unconscious mind responds to situations that reflect your goals (in this case being romance), so it's always good to trust your gut.
Summary: Be honest. Attend more events that interest you. Follow your instincts.

Problem: Article: To understand electronegativity, it's important first to understand what a "bond" is. Any two atoms in a molecule that are "connected" to each other on a molecular diagram are said to have a bond between them. This means that they share a set of two electrons with each atom contributing one electron to the bond. The exact reasons for why atoms share electrons and bond are a little beyond the scope of this article. If you want to learn more, try this article on the bond basics or WikiHow's own How to Study the Nature of the Chemical Bond (Chemistry). When two atoms share a set of two electrons in a bond, they don't always share them equally. When one atom has higher electronegativity than the atom it's bonded to, it pulls the two electrons in the bond closer to itself. An atom with very high electronegativity may pull the electrons all the way to its side of the bond, barely sharing them at all with the other atom. For example, in the molecule NaCl (sodium chloride), the chloride atom has a fairly high electronegativity and the sodium has a fairly low one. Thus, the electrons will get pulled towards the chloride and away from the sodium. An electronegativity table of the elements has the elements arranged exactly like in a periodic table, except that each atom is labeled with its electronegativity. These can be found in a variety of chemical textbooks and technical articles as well as online. Here is a link to an excellent electronegativity table. Note that this uses the Pauling electronegativity scale, which is most common. However, there are other ways to measure electronegativity, one of which will be shown below. If you don't have an electronegativity table handy, you can still estimate the strength of an atom's electronegativity compared to the strength of another element's atom based on where it is located on a normal periodic table. Although you will not be able to calculate a number value, you can evaluate the difference between the electronegativities of 2 different elements. As a general rule: An atom's electronegativity gets higher as you move to the right in the periodic table. An atom's electronegativity gets higher as you move up in the periodic table. Thus, the atoms in the top right have the highest electronegativities and the atoms in the bottom left have the lowest ones. For example, in the NaCl example from above, you can tell that chlorine has a higher electronegativity than sodium because it's almost all the way in the top right. On the other hand, sodium is far to the left, making it one of the lower-ranking atoms.
Summary:
Understand that chemical bonds occur when atoms share electrons. Understand how electronegativity affects the electrons in the bond. Use an electronegativity table as a reference. Remember electronegativity trends for easy estimations.
