Answer:
yes
Explanation:
Lavoisier's finding laid the foundation for modern chemistry and revolutionized science. The Law of Conservation of Mass holds true because naturally occurring elements are very stable at the conditions found on the surface of the Earth. Most elements come from fusion reactions found only in stars or supernovae.
The mass number is equal to the number of protons plus the number of neutrons. From the periodic table, we can see that chromium has an atomic number of 24, which means its nucleus contains 24 protons. ... Therefore, the chromium-52 isotope contains 28 neutrons in its nucleus.
Answer:
I think its epicenter
Explanation:
The epicenter is the point on the earth's surface vertically above the hypocenter, point in the crust where a seismic rupture begins.
Answer:
Hydrogen is the lightest element in the periodic table. Hydrogen is a gas of diatomic molecules and is colorless, odorless, non-toxic, and highly combustible. It is the most abundant chemical substance in the universe as it constitutes roughly 75% of all normal matter.
