Answer if you know the answer //Which of the following is an unusual property of water? A. Its atoms are bound by ionic bonds.
B. It doesn't exist in the gaseous state on Earth.
C. Its charge is balanced evenly around the atom.
D. It's a polar molecule.

H2O is covalent so A is false.

Water is in clouds so B is false.

Water is polar so C is false.

D is correct H2O has an imbalance of e- so it is polar.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
