Antimony,carbon sodium gallium
Answer:
244.76
Explanation:
The weight of grams by 1.82 moles of lithium carbonate would be: 134.481438 So we need to use this equation to find mass by grams m × g = ms Where m is for moles, g for grams, and ms for mass. So now we need use this equation: 1.82 × 134.481438 = ? 1.82 × 134.481438 = 244.75621716 244.75621716, rounded-up (to the nearest-tenths place) is 244.76. So now you have it! The mass of 1.82 moles of lithium carbonate is 244.76!
Answer:
A
Explanation:
this is because the electrons are attracted to the protons, the stronger the attraction and energy level the closer the electrons are to the nucleus. this moves them to a higher energy orbital. For example in a Bohr diagram.
Answer:
21H deuterium (D), 31H is tritium (T), 11H is hydrogen
Explanation:
11H: it has the greatest abundance, it has only one proton (it does not have neutrons).
21H (D): it has a proton and a neutron in its nucleus.
31H (T): it has a proton and two neutrons in its nucleus.
Remember that isotopes have the same atomic number, but a different mass number (elements in the number of neutrons differed).
