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 ...
Nitrogen \((Z=7)\) belongs to group V of the Periodic Table has five electrons in its outermost shell. Hence, its valency is \(8 -5 = 3\). Calculating Number of Neutrons We know that the atomic number of an atom of an element gives its number of electrons and protons. Then, what...
Number of neutrons in nucleus We know A=Z+n⇒n=A−Z A,B and C are the number of neutrons in hydrogen, helium and lithium. A+B+C= View Solution Knowledge Check The number of neutrons in an atom of Na is A23 B11 C34 D12Submit If A,Z and N denote the mass number, the...
Protons, neutrons, and electrons are found in all atoms except the common form of hydrogen. The number of protons in an element’s nucleus determines its atomic number. The number of protons in a neutral atom is equal to the number of electrons in shells, which is the energy level around...
What is the atomic number of mercury? What is the atomic number of chromium? Calculate the number of neutrons in a bromine nucleus, which has a radius of approximately 5.38 x 10-15 m. The atomic number of carbon is 6, the atomic number of chlorine is 17, and the atomic number of bro...
The nuclear notation of an atom or an ion shows the number of protons, the number of neutrons, and sometimes, the number of electrons. However, these are not presented as they are because they are encoded as the mass number and the atomic number. With this, it is easier ...
First, lithium element is used in medication for the treatment of Bipolar disorder, the US food and Drug Administration has given a green signal for its usage, as it helps to make patients calm quickly. In addition to this, Lithium carbonate also used in a small amount to prevent further ...
If the atomic weight is 4.001, you can be confident the atom is helium, with 2 protons and 2 neutrons. An atomic weight closer to 5 is more troublesome. Is it lithium, with 3 protons and 2 neutrons? Is it beryllium with 4 protons and 1 neutron? If you're not told the element name...
The only factor that can enhance the bonding caused by the nuclear factors is the third factor in reverse, i.e., when an even number of neutrons and protons are present. These trends combined tend to favor an increasing neutron/proton ratio for high mass number nuclides, and equal number ...
Lithium is a chemical element that is abbreviated 'Li.' Its name comes from the word 'lithos,' which is a Greek word that means 'stone.'Answer and Explanation: The mass number of lithium is 7. The mass number of any element is equal to its number of protons and neutrons. You can ...
