The radioactive decay of Ti- 206 to Pb-206 has a half life of 4.20 minutes. Starting with 5.00 × 20∧22 atoms of Ti-206, calculate the number of such atoms left after 42.0 minutes.

What is the atomic number of an atom that has 6 protons

How does climate change cause the ocean's thermohaline current to slow down?

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
