Hey there!
A half-life means after a certain amount of time, half of that substance will have decayed after that time.
An equation for exponential decay is the following:
y = a(1 - b)ⁿ
Where a is the original amount, b is the rate of decay, and n is time.
1000 is about 0.3 of a half life, 1000 divided by 138 days (3312 hours) is approximately 0.3.
Let's plug in values to that equation:
y = 321(1 - 0.5)^(0.3)
Simplify.
y = 260.73
There will be 260.73mg of polonium-210 remaining after 1000 hours.
Hope this helps!
Answer is: <span>the missing daughter nucleus is rhodium (Rh).</span>
Nuclear
reaction: ¹⁰⁶Ru → ¹⁰⁶Rh + e⁻(electron) +
ve(electron antineutrino).
Beta decay is radioactive decay in which a beta
ray and a neutrino are emitted from an atomic nucleus.There are two types of
beta decay: beta minus and beta plus.
<span>In beta minus decay,
neutron is converted to a proton and an electron and an electron antineutrino.
In beta plus decay, a proton is converted to a neutron and positron and an
electron neutrino, so mass number does not change.</span>
Answer:soda
Explanation:A homogeneous mixture is a mixture in which individual components of the mixture cannot be identified and since individual components of soda cannot be identified it is a homogeneous mixture
Answer:
Neutral atoms can be turned into positively charged ions by removing one or more electrons.
Explanation:
If there is an atom that has 9 protons and 9 electrons, removing an electron from the atom will gain a postive charge.
