Answer: A when going down the periodic table your atomic radius will get bigger same if you got to the side. B Moving left to right within a period or upward within a group, the first ionization energy generally increases
Explanation:
Answer 1.) Eu3+ ( Europium with charge of + 3 ) Answer 2.) Sn-188 with a -2 charge So, we know that 50 protons = the atomic mass= Sn (tin) Now, we have to find the atomic mass/ atomic mass= protons+neutrons/ plugin= 50 protons+ 68 neutrons= 118 amu (atomi mass unit) Then , we have 48 eletrons ( e-) - ( 50 protons ( positive chage ))= -2 charge! Final plugin: Sn-188 with a -2 charge.
Answer:
b. No
Explanation:
The question above is related to "The Law of Conservation of Mass." This law states that <u>mass is neither created nor can it be destroyed.</u> Even if a particular matter will be mixed with another substance or it undergoes chemical reaction,<u> the mass of the matter will remain the same.</u> Even with a change in phase, the mass of the matter will remain the same.
