Standard nuclear notation shows the chemical symbol, the mass number and the atomic number of the isotope. Example: the isotopes of carbon. The element is determined by the atomic number 6. Carbon-12 is the common isotope, with carbon-13 as another stable isotope which makes up about 1%.
More Easy Vegetables to Grow. Most root vegetables like carrots, turnips, and radishes are hardy and can be planted directly in the garden early in the spring and left until fall. The tops can be harvested too as these plants grow. Green beans and zucchini are also a cinch to grow and quite prolific producers.
What to grow. A wide range of common leafy vegetables, such as cabbage, Brussels sprouts, broccoli, kale and cauliflower are all part of the Brassica genus. Some root crops such as turnips, swedes and kohl rabi are also part of this nutritious group. Most brassicas are relatively easy to grow; however, unless you're an experienced gardener, cauliflowers are best avoided. For a first time grower, try a variety of cabbage, Brussels sprouts or kale.
