What is the number of protons, neutrons, and electrons in a sodium atom? What is the number of protons plus the number of neutrons in the nucleus of an atom equivalent to? (a) atomic charge (b) atomic number (c) mass number (d) atomic weight. What are the sy...
What is the mass number of an atom with 5 protons and 7 neutrons? 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 of 25 and 13 neutrons. what is the atomic number of this atom? What is the number of neutrons...
they range from 1 (the atomic number of hydrogen) to 118 (the number of the heaviest known element). As more elements are discovered, the maximum number will go higher. Theoretically, there is no maximum number, but elements become unstable with more and more protons and neutrons, making...
For most atomic nuclei, the maximum number of neutrons that can be bound is unknown. The discovery of two neutron-rich nuclei — and the confirmed absence of others — might help solve this conundrum. Stars are element factories. Every atom in the Uni...

Complete the table to show the number of subatomic particles present in the nuclei of these two isotopes of hydrogen.(1)Isotope Number of protons Number of neutrons}H H(ii) Use the dat a in the table to explain the term isotopes.(2)(b)The relative atomic mass of hydrogen in the ...
To understand the atomic radius definition, one must first consider the subatomic particles: electrons (negatively charged particles) orbit an atom's nucleus (center of the atom), which contains protons (positively charged particles) and neutrons (electrically neutral particles). The atomic radius of...
Protons have a relative mass of 1, which is the same as the relative mass of neutrons. The number of protons in an atom is called the 'Atomic Number' of that atom and is sometimes referred to as 'Z'. This is important because it defines the type of atom, i.e. which element it ...
View Solution Atomic number of an element is 30 and its atomic weight is 65 . The number of protons and neutrons are View Solution Atomic number of an element is 30 and its atomic are weight is 65. The number of protons and neutrons are ...
Mass Number It is the sum of neutrons and protons of an atom present in nucleus. Mass Number for two different atoms can be same. The Atomic Mass of an atom is approximately equal to its Mass Number as mass of a neutron as well of a proton is one unit on atomic mass scale. Post ...
