soluble substances dissolves in solvents
Answer:
Yes the two of the answer is True
Explanation:
In a magnetic field, the radius of the charged particle is as follows.
r = 
where, m = mass, v = velocity
q = charge, B = magnetic field
Therefore, q will be calculated as follows.
q = 
= 
= 
= 
= +2e
Thus, we can conclude that the charge of the ionized atom is +2e.
Answer:
A = 8
B = 8
C = O ( Oxygen )
D = 26
E = 30
F = Fe (Iron)
Explanation:
1)To get "A" we use the following formula
mass number = number of protons + number of. neutrons
15 = number of protons + 7
15 - 7 = number of protons
8 = number of protons
A = 8
2)To find "B"
atomic number = number of protons
Atomic number = 8
B = 8
3)To find "C"
the atomic number is 8 so the element which
has 8 atomic number on periodic table is Oxygen.
C = oxygen
4) To get "D"
Number of protons = atomic number
number of protons = 26
D = 26
5)To get "E"
mass number = number of protons + number of. neutrons
56 = 26 + number of neutrons
56 - 26 = number of neutrons
number of neutrons = 30
E = 30
6) To find "F"
The atomic number is 26 so the element which has 26 atomic number on periodic table is Iron.
