2、 atomic number and the number of protons related to each other?How do the number of protons, number of neutrons, and the mass number relate to each other?What is the one thing that determines the identity of an atom (that is, whether it is an oxygen atom or a carbon atom, etc....
mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen ...
Definition Oxygen is a chemical element with atomic number 8, represented by the symbol O. The name oxygen was coined in 1777 by Lavoisier. Its name derives from the Greek word "oxys" meaning "sharp," referring to the sharp taste of acids, and "gen膿s" meaning "producer." It is a ...
Oxygen (Atomic # 8) has eight protons in its nucleus. • Atoms are electrically neutral. • Therefore • # of protons in the nucleus = the # of electrons around its nucleus Atomic Number • Hydrogen has one proton in the nucleus, and 1 electron around its nucleus. • Oxygen has...
For example, all carbon atoms have the atomic number of 6, whereas all atoms of Oxygen have 8 protons in their nucleus. What is Mass Number? The number of protons and neutrons combine to give us the mass number of an atom. It is represented using the letter ‘A.’ As both protons an...
Second, the equipment used at the time to determine mass ratios was not very accurate. Still, his table was an important first step in determining atomic masses. Some of the values that he reported in that first table were: nitrogen: 4.2; carbon: 4.3; oxygen: 5.5; phosphorus: 7.2; and ...

The number of protons in an atom is similar to the DNA of a human; it is responsible for giving the atom its most notable characteristics. The atomic numbers of some of the most famous atoms are hydrogen (1), oxygen (8), carbon (6), nitrogen (7), and gold (79) as seen in the...
