What else can I help you with?
Is this true or false Hydrogen-1 and hydrogen-2 differ in that hydrogen-2 has one neutron hydrogen-1 has none?
Yes it is true. All isotopes differ in the number of neutrons only.
When a unstable isotope decays the daughter isotope that result is always a stable isotope true or false?
False. When an unstable isotope decays, the resulting daughter isotope may or may not be stable. Some daughter isotopes are stable, while others may still be radioactive and undergo further decay.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
When an unstable isotope decays the daughter isotope that results is always a stable isotope true or false?
Technically the answer is false, however the answer most tests accept as the correct answer is True.According to Nuclear theory when a parent undergoes decay and produces a daughter isotope the daughter may be stable or it may be unstable and further decay until a final stable granddaughter isotope is formed. This process is called a decay chain, however since eventually a stable isotope is formed the acceptable answer is True, even though technically it is not the case.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
When a certain isotope such as Pu 239 is hit by a neutron it will always split into the same smaller nuclei true or false?
false

When a certain isotope such as Pa-231 is hit by a neutron it will always split into the same smaller nuclei?
false
Neutron has a charge of plus 1 true or false?
false
State true or false Hydrogen is insoluble in water?
False False False FalseFalse
Is it true that A proton is 24 times more massive than a neutron?
False. The mass of proton and neutron are almost similar.
True or false that hydrogen is the least common element in the universe?
False. Hydrogen is the most abundant element in the universe, constituting about 75% of its elemental mass.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons

When a certain isotope such as U 238 is hit by a neutron it will always split into the same smaller nuclei?
No, not at all. Simple decay (alpha decay, beta decay, K capture, etc.) will always produce the same daughter products, but with neutron-induced fission it's ... well, it's not quiterandom, but it's certainly not going to always produce the same products.

True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
