The answer to your question is dependent variable.
Answer:
Explanation:
There are only two elements in the first period: hydrogen and helium. We can explain why there is less elements in the first row in modern theories of atomic structure.
Answer:D)
Explanation: the distance traveled over time
Well knowing the number of protons, you can find what the element is, which is Ti = titanium. Then to find the charge, simply subtract 22 and 18 which is +3.
Find the mass number by adding 22 and 34 = 56.
56. +3
Ti
22
This would be the correct notation in isotopic form.
B 2
is which shell are the valence electrons of the elements in period 2 found
