Answer:Radioactive
Explanation:
The radioactive nucleus is the one which does not has enough binding energy to hold the nucleus in a stable state and thus radiates either electron or proton to become a stable element.
A radioactive element is formed when after billions of years such as uranium and thorium. The stability of the nucleus depends upon the opposition of attractive and repulsive force among the nucleus.
Answer:
10.21 N
Explanation:
As the force is a vector, it can be decomposed in two components perpendicular each other, so there is no projection of one component in the direction of the other.
When divided in this way, the magnitude of the resultant vector can be found simply applying trigonometry, as follows:
F² = Fx² + Fy² ⇒ F = √(Fx)²+(Fy)²
Replacing by Fx= 5.17 N and Fy = 8.8 N, we get:
F = √(5.17)²+(8.8)² =10.21 N

Answer : The total electric charge of electrons is, 
Explanation:
Answer : The number of electrons transferred are, 
Explanation :
First we have to calculate the number of electrons.
Number of electrons = 
Mass of 1 electron = 
Total mass of electron = 2.5 kg
Number of electrons = 
Number of electrons = 
Now we have to calculate the total electric charge of electrons.
Formula used :
where,
n = number of electrons transferred =
Q = charge on electrons = ?
e = charge on 1 electron = 
Now put all the given values in the above formula, we get:
Thus, the total electric charge of electrons is,
