Answer:

Potassium

1s2 2s2 2p6 3s2 3p6 4s1

Explanation:

The atom having only one electron its outermost shell must belong to an element in group one of the periodic table.

Having noted that, we proceed to find out what element in group one that has the atom just described in the question.

That atom must belong to an element in the fourth period. The only group 1 element in the fourth period is potassium.

The electron configuration of potassium is;

1s2 2s2 2p6 3s2 3p6 4s1

What term best defines the splitting of nuclei into smaller fragments due to the bombardment of neutrons?
Andre45 [30]
Well the knowing what the answer choices mean would be most helpful for this problem:

a.  The definition of "Fusion" in general means bringing things together into one unit. In biology, Fusion sometimes refers to cellular fusion, the bringing of two or more uninuclear (cells with one nucleus) together to form multinuclear cells.
B. Fission is almost the opposite of "fusion" in that it is the action of dividing or splitting into two or more parts. This sounds like fission of a heavy nucleus to me.
c. molecular blending forms polymers. So this choice is incorrect.
d. atomic rebonding- when atoms on different molecules combine to form diatomic ions.

hope this helped!

Put the steps of the scientific method into the correct order.
riadik2000 [5.3K]
<span>The scientific method is a systematic way of questioning about the world around us and answering questions. The number of steps varies from one description to another, mainly when data and analysis are separated into separate step, but this is a fairly standard list of 6 scientific method steps, which you are expected to know for any science class:

1. Form a Hypothesis. This is a sort of educated guess about what you expect. 
2. Design an Experiment to test your hypothesis. An experiment has an independent and dependent variable. You change or control the independent variable and record the effect it has on the dependent variable.
3. Conduct Experiment
4. Record data and observations and analyze what the data means. Often, you'll prepare a table or graph of the data.
5. Form a Conclusion. Conclude whether to accept or reject your hypothesis. Communicate your results.</span>
