Most elements in the "d-block" of the periodic table (groups 3 through 12) are considered transition metals. Unlike other elements, they can form more than one type of ion. When a transition metal is part of an ionic compound, a Roman numeral is included to specify which ion is involved. For example, copper sometimes forms an ion with a charge of +1, and sometimes with a charge of +2. Copper (I) chloride and copper (II) chloride are 2 different ionic compounds. The Roman numeral tells you which copper ion is part of the compound. The first word of the compound name represents the metal ion, or cation. This is always positively charged. Just add the Roman numeral as a positive charge to the element name: For example, copper (II) chloride includes the cation Cu2+{\displaystyle Cu^{2+}}, since II is the Roman numeral for 2. The second word of the compound name represent the anion. This is the negatively charged ions that form from non-metallic elements. Each element of this type only forms 1 ion. To find the charge of that ion, look it up in a textbook or chemistry website, or memorize the group rules. For example, chloride is the name for a chlorine ion. Chlorine, like similar group 17 elements, forms ions with a charge of negative one. This is written as Cl{\displaystyle Cl^{-}}. This process is the same as for any ionic compound. The total positive charge from the cations always balances out the total negative charge from the anions. The net charge of the ionic compound is always zero. To balance out the 2+ charge from a Cu2+{\displaystyle Cu^{2+}} ion, you need 2 Cl{\displaystyle Cl^{-}} ions (2 ions x -1 charge per ion = -2). This makes an ionic compound with a net charge of +2 -2 = 0. As always, the number of atoms is written as a subscript after the element name. You do not need to write the charges in the final formula: Copper (II) chloride has one copper atom and two chlorine atoms. The formula is CuCl2{\displaystyle CuCl_{2}}.

Summary: Find the Roman numeral in the compound name. Find the charge of the cation. Find the charge of the anion. Balance the charges. Write the chemical formula.

Divorced men are at greater risk for a range of health problems, so strive to make your health a priority. Eat a real, whole foods diet, get at least 8 hours of sleep nightly, exercise daily, and create a routine to manage stress. Reconnect with yourself by taking time for interests and passions that you neglected before. Restart your weekend karate classes, join Toastmasters if you love public speaking, or carve out time for a hike on Saturday mornings. Spending time doing things you love will help you to move forward with your life in a positive way. You might feel overwhelmed about taking on duties that your spouse once took responsibility for. If you're having trouble, seek out help. Most communities offer resources like child care assistance and personal finance workshops that can help you adjust to new roles. Consider asking around at your local library to learn about practical classes or services offered in your area. Whether you're splitting custody with your ex or only seeing your kids on weekends, you still need to devise some structure when they're in your care. Brainstorm a few ways to make them comfortable when they're at your place. Stock your fridge and pantry with kid-friendly foods, set up a space for them to do their homework, or purchase games or movies that you can enjoy together during leisure time. You'll also want to come to an agreement with your spouse about parenting strategies, so your kids are receiving relatively consistent rules and discipline.

Summary: Support your health and wellness. Develop your hobbies. Access resources if you need them. Establish a routine with your children.

You must be at least 21 years old, with a personal license and personal auto insurance. You must own a car, and you must have a clean driving record. You must own an iPhone (4S or newer) or Android (2013 or newer), or rent a smartphone from Uber. Your vehicle must be a 2000 make or newer; it must have four doors, and it may not be salvaged. If you don't have a vehicle, Uber can help you get loans and discounts. It should come as no surprise that the money you will earn as an Uber driver will be directly impacted by how expensive it is for you to maintain your vehicle. As such, you should: Apply with a car that gets a large number of miles per gallon. Apply with a car that is new and in good condition and unlikely to need frequent repairs resulting of several hours on the road each day. Keep in mind, however, that there is a tradeoff between an expensive car that is cheap to maintain and an economical car that requires a lot of maintenance. If you have a car that qualifies for one of these services, you can claim a higher base fare rate and claim a higher price per mile and per minute when giving rides to customers. Such cars include (but are not limited to): Acura RDX/MDX/TLX+ Audi A3/Q3/S4/A6/Q7+ BMW X3 & X5 BMW 5 Series & 7 Series Cadillac CTS, Escalade, SRX+ Hyundai Genesis Sedan Infiniti EX/FX/QX/Q50+ Lincoln Navigator Porsche Macan/Cayenne Mercedes-Benz C/G/CLS/GL+ Class Tesla Model S Buick Enclave/Regal/LaCrosse Land Rover Discovery Lexus GS/LX/GX/RX+ Land Rover Evoque Kia K900
Summary: Determine whether you are eligible to drive. Apply with an economical car. Consider applying to drive for UberBLACK, UberSUV or UberSELECT.
