Alpha partical is a He nucleus. When decaying alpha particle mass is reduced by 4 and atomic number is reduced by 2.

The actual element which has 102 protons is No (Nobelium). 
Since it has 167 neutrons, the mass = protons + neutrons = 102 + 167 = 269

after an alpha decay, the new element formed has 100 protons which is Fm ( Fermium)

the alpha decaying equation is,

    ₁₀₂²⁶⁹No → ₁₀₀²⁶⁵Fm + ₂⁴α + heat

the total mass and the atomic number( numbe rof protons) must be equal in both sides.

Why can’t there be a temperature lower than absolute zero
Firdavs [7]
Atoms cannot physically get more compact (temperature lowering increases the space between atoms) At absolute zero, the atoms are as physically close together as allowed by the physical laws governing it.

Water is wet. true or false? Why?
Vikentia [17]

True water is wet because when something is wet in this case it's water it has water on it at a molecular level. Water molecules are bonded on top of each other so it's wet.
