The Abacot Ranger duck is a utility breed which was mainly developed for eggs and meat production. It is classified as a light weight duck breed and also known as Hooded Ranger and Streicherente. The breed was developed by Oscar Grey of Friday Wood near Colchester, Essex, United Kingdom.
Best Answer: Generally, the elements become more reactive as you move down and to the left (in a diagonal line). As you move down, the outer electron shells are positioned further away from the positive nucleus, with the electrostatic force holding the element together growing weaker (due to increased distance).
That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells. Because they are so close to being happy, they have the trait of combining with many different elements. They are very reactive. You will often find them bonding with metals and elements from Group One of the periodic table. The elements in the column on the left each have one electron that they like to donate. We've just told you how reactive the halogens are. Not all halogens react with the same intensity or enthusiasm. Fluorine is the most reactive and combines with most elements from around the periodic table. Reactivity decreases as you move down the column. As you learn more about the table, you will find this pattern true for other families. As the atomic number increases, the atoms get bigger.
