What is atomic mass of $$He$$ in amu $$(u)$$ units?

Answer the question:
A nuclide has the symbol $$^{22}_{10}Ne,$$
What is the proton number of a nucleus of this nuclide ?

A stationary body explodes into two fragments each of rest mass 1kg that move apart at speed of 0.6c relative to the original body. The rest mass of the original body is:-

A radioactive nucleus undergoes a series of decays according to the sequence
$$A\overset{\beta}{\rightarrow}A_1\overset{\alpha}{\rightarrow}A_2\overset{\alpha}{\rightarrow}A_3$$
If the mass number and atomic number of $$A_3$$ are $$172$$ and $$69 $$respectively, then the mass number and atomic number of A is

Atomic masses of $$^{14}_{7}N$$ and $$^{16}_{8}O$$ are $$14.008$$ amu and $$16.000$$ amu respectively. The mass of $$^{1}_{1}H$$ atom is 1.007825 amu and the mass of neutron is $$1.008665$$ amu. Pick the correct option 

The mass of chlorine ($$_{17}Cl^{35}$$) atom is 34.98 amu, mass of proton = 1.007825 amu, mass of neutron= 1.008665 amu. Then binding energy is :

The energy required to separate the typical middle mass nucleus $$^{120}_{50}Sn$$ into its constituent nucleons is :
(Mass of $$^{120}_{50}Sn=$$ $$119.902199\  amu$$; mass
of proton$$=1.007825\  amu$$ and mass of neutron$$=1.008665\  amu$$)

In the reaction $$_7N^{14} +$$ $$ _2He^4 \rightarrow  _8O^{17} + $$ $$_1H^1$$. The minimum energy of $$\alpha$$-particle is
$$M_N=$$ $$14.00307$$ amu      $$M_{He}=$$ $$4.00260$$ amu
$$M_o =$$ $$16.99914$$ amu      $$M_H=$$ $$1.00783$$ amu
