Atomic Number (Z) = Number of protons =Number of electrons. For example, an atom of magnesium contains 12 protons, therefore, its atomic number is 12. All the atoms of a particular element contain same number of protons in their nuclei. Therefore, all the atoms of an element have same atomic number.
The thyroid gland is an organ located in the front of your neck and releases hormones that control your metabolism (the way your body uses energy), breathing, heart rate, nervous system, weight, body temperature, and many other functions in the body.
Your thyroid gland is a small gland, normally weighing less than one ounce, located in the front of the neck. It is made up of two halves, called lobes, that lie along the windpipe (trachea) and are joined together by a narrow band of thyroid tissue, known as the isthmus.very cell in the body depends upon thyroid hormones for regulation of their metabolism. The normal thyroid gland produces about 80% T4 and about 20% T3, however, T3 possesses about four times the hormone strength as T4.
