Oxygen is a non metal element. Mass number of it is 16.
Oxygen is a non metallic element. Mass number of it is 16.
Sulfur- Element Number 16 on the Periodic Table of Elements
Oxygen is a non metal element. Atomic mass of it is 16.
Oxygen is a non metal element. Atomic mass of it is 16.
Oxygen is a non metal element. Atomic mass of it is 16.
This element is oxygen (O).
That would be oxygen (16O).
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16.
The formula mass of a compound that contains the element would be a larger number than the mass number of the individual element. The individual element would simply be the mass of just that one atom, where as the compound would be the mass of that atom plus the other masses of the other atoms that make up the compound. ex. Oxygen-O has a mass number of about 16 grams. Water-H2O has a formula mass of 2 x mass of Hydrogen-H (about 1) + the mass of Oxygen-O 16 = 18 grams. A formula mass of 18 g is more than a mass number of 16 g.
Well, if an atom has 16 protons, then it is Sulfur, which is a non metal. If it had 16 neutrons, then it would be another isotope of sulfur, which would make it Sulfur-32. Then, unless it has a charge, there would also be 16 electrons.
The atomic number refers to the number of protons in the element. And since the number of protons = number of electrons, the atomic number is also the number of electrons in the element. The mass number of an element refers to the number of neutrons and protons in the element. &since electrons are negligible in mass, the number of neutrons can be found out by subtracting the atomic number from the mass number. Take for example, oxygen. Oxygen has an atomic number of 8 and a mass number of 16. Hence, from the atomic number it can be derived that it has: 8 electrons 8 protons While from the mass number, it can be derive that it has: 16-8 = 8 neutrons
The element with a mass number of 16 and atomic number 8 is oxygen. It has 8 protons and typically 8 neutrons in its nucleus, giving it a mass number of 16, which is the total number of protons and neutrons.
