The condensed electron configuration of this element might be is 8s^25g^6. The electronic configuration is a depiction of the distributions of different or various physical elements such as atoms, molecules, and also the electrons. The electronic configuration is said to be like a code that explains the relationships of electrons.

Answer:

5g2 6f2 7d1 8s2 8p1

Explanation:

The full electrons configuration for this element would be:

1s2 2s2 2p6   3s2 3p6 3d10   4s2 4p6 4d10 4f14   5s2 5p6 5d10 5f14 5g2    6s2 6p6 6d10 6f2    7s2 7p6 7d1   8s2 8p1

This configuration explains the electron orbit levels and the arrangement of all the electrons for that element. Each element has its own electron configuration. The configuration shown for element-126 is only a prediction, as the element is not naturally occurring on the planet.

Mrs. DeFord wanted to know whether or not her students would do better on a quiz if she promised them candy.
marta [7]

Answer:

a.) Independent Variable: # of candy bars promised to each group

[ The Independent Varaiable is what you change in the experiment]

b.) Dependent Variable: Quiz Scores

[ The Dependent Variable is what you're testing in the experiment; what the experiment should affect]

c.) Constant(s): Same Quiz, same number of gender kids in each group, same age kids in each group, same ability, and same background. [and same time, I'm assuming.]

[Constants are what you keep the same in the experiment; what you're not changing.]

d.) Testable Question: Will promising kids candy make them do better on tests and quizzes? [or something along this lines of this]

[The Testable Question is what you're trying to find out in the experiment]

e.) Hypothesis: The more candy the students were promised, the better results Mrs. DeFord would get from them.

[The Hypothesis is what the person performing the experiment expects will happen; an educated guess]

f. Formal Conclusion: Data shows that kids who were promised more candy had a better average than kids who were promised less candy/none. Mrs. DeFord's hypothesis was correct, since she assumed the more candy the students were promised, the better they would do on the quiz.

[The Formal Conclusion is what you have learned from the experiment, and wether or not the hypothesis was correct or not.]

I hope this helps! :)

How did the discovery of isotopes help to lead to a revised model of atomic structure?
Arte-miy333 [17]
Dalton postulated that atoms of the same elements had the same mass while atoms of different elements had different masses. 

The discovery of isotopes revealed that atoms of the same element did not necessarily have same masses, they could have different masses.

Therefore, the modern periodic table that we use nowadays contains the average atomic mass of all the isotopes found for a given element.
