Every nucleus of a given element must contain the same number (Z) of protons, but these nuclei can contain different numbers of neutrons. Most hydrogen atoms have nuclei that consist of a single proton, but a small fraction (about 0.015 percent) of the hydrogen atoms that occur in Nature ...

Oxygen has eight total electrons — two orbit the nucleus in the atom's inner shell and six orbit in the outermost shell. The outermost shell can hold a total of eight electrons, which explains oxygen's tendency to react with other elements: Its outer shell is incomplete, and electrons are...
Atom X has 17 protons. How many electrons are in its valence shell (outermost energy level)? A) 10 B) 3 C) 7 D) 5 If carbon has an atomic number of 6, and a mass number of 14, how many neutrons are in the atom? The at...
The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. Relative Atomic Mass The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mass is also ...
What is the mass of this atom? What is the molecular weight of nitrogen? An atom of nitrogen has seven protons in its nucleus. How many electrons does it have? An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom? An atom has a mass number o...
What is oxygen, how many electrons, protons, neutrons, and valence electrons does it have, its symbol, molar mass, electron configuration, what is it used for
An atom having atomic mass number 13 has 7 neutrons. What is the atomic number of the atom. View Solution Define the term - 'mass number of an atom. If an atom 'B' has mass number 35 & atomic number 17, state the number of protons, electrons & neutrons it contains. View Solutio...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
Conversely, rare are the compounds in which electrons are torn away (or more precisely, pulled away) from the oxygen atom (as in F2O and F2O2). In the past, proceeding solely from the position of oxygen in the periodic system, a negative charge ( — 2) was ascribed to the oxygen ...
