The chemical nature of an atom, that is , the chemical properties of a specific element, is determined by the number of protons in the nucleus<span>. This number of protons is called the </span>atomic number<span>. The mass of the atom, its atomic mass, depends upon both the number of protons and upon the number of neutrons present in the nucleus (remember that the mass of an electron is so small that it is simply ignored for the purpose of establishing the atomic mass).</span>The difference between atoms, ions and isotopes is the number of subatomic particles.<span> An atom is the basic building block of matter, the smallest molecule of an element that exists and that cannot be chemically divided by ordinary means. Each atom is comprised of protons, neutrons and electrons. In ions, the number of electrons differs, and in isotopes.

Abdominal Thrusts or commonly referred to as the "Heimlich Maneuver". It is known as a method of aiding upper airway obstructions or "choking" for short. Upper airway obstruction can be caused by different foreign objects such as food. The Heimlich Maneuver was named after Dr. Henry Heimlich, who first described the maneuver in 1974.
Answer:
a neutral charge
Dad I'm so taking electron so it would be a neutral charge because it will do something
The answer is; B is younger than D
In sedimentary rocks, the bottom layers are older that overlaying layers. This is because sediments are placed on top of each other by surface runoffs to ocean beds. Therefore, the first sediments to be deposited will always be towards the bottom as more and newer ones are brought in and deposited.
While taking its meal (usually between dusk and dawn), an infected mosquito injects immature forms of the parasite, called sporozoites, into the person's bloodstream. The sporozoites are carried by the blood to the liver, where they mature into forms known as schizonts.
