Web the total number of protons and neutrons in an atom is called its mass number (a). Web an atom of an element 2 has 22 neutrons and 18 protons in its nucleus.what are the (1)mass number (2) valence electron and (3)group no. Atoms of all elements (except for most atoms of hydrogen) have neutrons in. The atomic number of a sodium atom is 11. Web however, carbon atoms may also have 7 or 8 neutrons. Web and the element with atomic no. Web titanium is the element having 22 protons and 21 neutrons. Now we need to find the mass number of argon. Since carbon comes in more than one variety due to differing numbers of neutrons, carbon is said to come in more than. 22 how many neutrons does this.
Web and the element with atomic no. Now we need to find the mass number of argon. Remember that protons are positive, and neutrons are neutral. Web and the element with atomic no. Because m ass number − atomic number = n o of. Web however, carbon atoms may also have 7 or 8 neutrons. Web some elements can only exist in an unstable form (for example, uranium). Web the total number of protons and neutrons in an atom is called its mass number (a). Hydrogen is the only element whose isotopes have unique names: Atoms of all elements (except for most atoms of hydrogen) have neutrons in. The number of neutrons is therefore the difference between the mass.
