Answer:

Explanation:
Let's firstly identify the atomic number (the number of protons) of Pu. This is done by referring to the periodic table and finding Pu. The atomic number of Pu is:

In order to identify the type of a nuclear decay, we need to find the N/Z ratio. This is the ratio between the number of neutrons and the atomic number of an isotope. The number of neutrons is found by subtracting the number of protons from the mass number:

That said, the N/Z ratio equation becomes:

This is a relatively high number thinking about the belt of stability of isotopes. Ideally, stable isotopes with a low Z value have an N/Z ratio of 1. Heavier isotopes with Z > 50 would have a slightly higher N/Z ratio and would be stable around N/Z = 1.25. This means we wish to decrease the N/Z ratio as much as possible.
Among all the decays, alpha-decay is preferred to decrease the N/Z ratio significantly (1.45 is much higher than 1.25). That said, we'll release an alpha particle with some nucleotide X of mass M and atomic number Z:

According to the mass and charge conservation law:


Identify an element with Z = 92 in the periodic table. This is uranium, U:

Answer:
Since hawks eat rabbits the rabbit population may decrease... severely
Answer:
Name: Magnesium
Atomic Number: 12
Atomic Mass: 24.305 atomic mass units
Number of Protons: 12
Number of Neutrons: 12
Answer:
1. 18 protons
2. Argon
3. 18 electrons
4. 8 electron
5. Neutral Atom
Explanation:
count the number of electrons on the shells, number of electrons is equal to the number of protons for a neutral Atom.
since the number of proton is 18 then the element is Argon which has an atomic number of 16.
Answer:
38.4 atm.
Explanation:
- We can use the general law of ideal gas:<em> PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂).</em>
P₁ = 3.0 atm, V₁ = 3200 L,
P₂ = ??? atm, V₂ = 250.0 L.
∴ P₂ = (P₁V₁)/(V₂) = (3.0 atm)(3200 L)/(250.0 L) = 38.4 atm.
