Is a period of an element the amount of time it takes for half of a radioactive isotope to decay?
False- the period is the horizontal row the element is in
What is the beta decay of radium 226?
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
What are the three products of radioactivity decay?
alpha decay, beta decay, and gamma radiation
What type of nuclear decay produces energy instead of a particle?
gamma decay
What is the nuclear equation for the decay of Po210 if it undergoes 2 alpha decay then a beta decay followed by another alpha decay.?
92Au 282Xe +13S
What is the product of a beta emission from strontium-90?
Yttrium-90 "the slash is important"
Strontium decays by beta decay part of the nuclear equation is shown below fill in the blank with a number?

The half-life of strontium-90 is 28 years How long will it take a 76 mg sample to decay to a mass of 19 mg?
56 years
What is the nuclear decay equation for uranium-238 to strontium-90?
The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.
What happens to a graph that is representative of exponential decay?
As time passes - as the graph goes more and more to the right, usually - the graph will get closer and closer to the horizontal axis.
Is a period of an element the amount of time it takes for half of a radioactive isotope to decay?
False- the period is the horizontal row the element is in
Can somethings decay constant change. ive been asked this question. the isotope strontium-90 has half life of 28 years Calculate its decay constant in units of year-1 and second-1. please help?
Decay constant and half life are mathematically related. One cannot change without the other changing, so - no - an isotope's decay constant cannot change.Do not confuse this with the fact that isotopes form other isotopes as they decay, and those other isotopes might have different half lives, so the gross observation of total activity may seem to indicate a change in rate - the reality is still no - the decay constant of a particular isotope does not change.
What is the nuclear decay equation for strontium 90?
Since the atomic number of Sr is less than 90, Sr undergoes beta decay. Beta decay is when the element decays into another element and a neutron actually breaks apart (sort of) into an electron and proton; the proton attaches to the other element, but the electron stays alone. Thus: 90------>90 Y+e0-1 38 Sr--->39 Y+e *there should only be one e, and the 0 and -1 should be in front, just like with the elements, but the format deletes the extra spaces so i put it like that for clarity's sake. sorry!
Order gamma decay beta decay and alpha deacy form weakest to strongest?
gamma decay beta decay alpha decay
What is relative decay?
I believe relative decay is the decay over time.

What does the decay of actinium turn into?
The natural isotope 227Ac decay: - by beta minus decay: to 227Th - by alpha decay: to 223Fr
