False, If something doesn't support your hypothesis maybe it was wrong in the first place and you should make it known in your research if you come up with a different conclusion.
Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).
Hydrogen is an element with atomic number 1. It has three isotopes:
1) protium (₁¹H), with mass number 1 (no neutrons).
2) deuterium (₁²H), with mass number 2 (one neutrons, n° = 2 -1, n° = 1).
3) tritium (₁³H), with mass number 3 (two neutrons, n° = 3 -1, n° = 2).
D
A describes liquid, b describes solid, and c describes solid as well. therefore d is the only good answer
Answer:
-23.333 °C
Explanation:
(-10°F − 32) × 5/9 = -23.33°C
the alkaline eart metal s are
Beryllium
Magnesium
calcium
Strontium
barium
out of these Magnesium reacts with oxygen and produces bright light due to formation of MgO
all other metals also form oxides but the oxide of Mg is brightest
