Answer:
The new element will be thorium-226 (²²⁶Th).
Explanation:
The beta decay is given by:
Where:
A: is the mass number
Z: is the number of protons
β⁻: is a beta particle = electron
: is an antineutrino
The neutral atom has 88 electrons, so:
Hence the element is radium (Ra), it has A = 226.
If Ra undergoes 2 rounds of beta minus decay, we have:
Therefore, if a neutral atom with 88 electrons undergoes 2 rounds of beta minus decay the new element will be thorium-226 (²²⁶Th).
I hope it helps you!

Answer:
The correct answer is - 5L.
Explanation:
From the ideal gas equation -
pv=nRT
p = pressure
v =volume
Here nRT is constant so
P would be inversely proportioned to v
So, p1/p2 = v2/v1
Putting values:
2/4(2) = v2/20 (p2 = 4 times of P1)
2/8 = v2/20
V2 = 5
Thus, the correct volume at new pressure would be - 5 L.
