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.

How does a phase change from solid to liquid occur in a substance?
Alex

Answer:

see below

Explanation:

1. Heat energy is added to the substance, weakening the electrical attraction between molecules.

2. Both the melting point and boiling point are lower.

3. dipole

4. Water and ethanol have different molecular structures.

5. The lone pairs of electrons in the oxygen atom causes the molecule to be bent; the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges.

Predict the shape of the molecule.
balandron [24]

Answer:

B.) trigonal bipyramidal

Explanation:

A.) is incorrect. In octahedral molecules, the central atom is bonded to six other atoms.

B.) is correct. In trigonal bipyramidal structures, the central atom is bonded to five other atoms.

C.) is incorrect. In tetrahedral molecules, the central atom is bonded to four other atoms.

D.) is incorrect. There is not such thing as a pyramidal molecular shape. This term is most likely referring to the shape, trigonal pyramidal. However, this is still incorrect. In trigonal pyramidal molecules, the central atom is bonded to three other atoms and a lone pair of electrons.
