How may protons neutrons and electrons In lawrencium?

Number of neutrons = Atomic mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.


What is the number of neutrons and electrons of mercury?

The atomic number of Mercury(Hg) is 80; since atomic number of an atom= No. of protons.Thus No. of protons in Mercury is 80. Also No. of protons = No. of electrons (In an neutral Atom; which is not an ion).Therefore No. of electrons is also 80. Next, Mass number(Atomic Mass) of Mercury is 160. Mass Number(Atomic Mass)= No. of Protons + No. of Neutrons. Hence calculating that we get No. of Neutrons also to be 80. FYI; Electrons have negligible mass so they are not included in calculating Mass of an atom, which only requires the nucleus which contains only protons and neutrons


Isotope with 13 protons and 14 neutrons?

The isotope that has 13 protons and 14 neutrons is aluminum.


How many protons neutrons does oxygen have?

oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)


How many protons neutrons and electrons does ununseptium have?

Ununseptium, with the atomic number 117, has 117 protons and 117 electrons. Since it is a heavy and unstable element, the number of neutrons can vary depending on the isotope, but a common isotope of ununseptium might have around 176 neutrons.

How does the atomic number relate to the number of protons in an atom?

Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)


If an isotope of silicon has 15 neutrons what is its mass number?

The mass number of an isotope is the sum of its protons and neutrons. Since silicon has 14 protons, the isotope with 15 neutrons would have a mass number of 14 (protons) + 15 (neutrons) = 29.

How many neutrons in isotope?

It depends on what isotope you're talking about. To find the number of neutrons in a particular isotope, take the atomic mass and subtract the atomic number. For example, Na has a mass of roughly 23amu and 11 protons, so an Na-23 atom would have 12 neutrons.
