What is wrong with carbon dating?
What is wrong with carbon dating? The group theorizes that large errors in carbon dating result from fluctuations in the amount of carbon 14 in the air. Carbon dating is unreliable for objects older than about 30,000 years, but uranium-thorium dating may be possible for objects up to half a million years old, Dr. Zindler […]
Why is Al3+ smaller than Na+?
Why is Al3+ smaller than Na+? Al3+ because they all have the same number of electrons, however Al3+ has the most protons and therefore greatest nuclear charge. In Al3+, the same number of electrons are being attracted by more protons in the nucleus, so the electrons are being pulled closer to the nucleus, reducing the […]
