Yes, horizontal rows are periods. “All of the elements in a period have a similar number of atomic orbitals. Each element in the top row (the principal time frame) has one orbital for its electrons. The greater part of the components in the second column (the second time frame) has two orbitals for their electrons. It goes down the occasional table that way. As of now, the most extreme number of electron orbitals or electron shells for any element is seven."<span>

<span>The vertical columns are groups. "The elements in a group have the same number of electrons in their outer orbital [and thus the same charge]. Every element in the first column (bunch one) has one electron in its external shell. Each element on the second segment (assemble two) has two electrons in the external shell. As you continue tallying the segments, you'll know what numbers of electrons are in the external shell.</span></span>

Scrat [10]

Answer:

Following are the correct code to this question:

phrase = "abcdefgh"#defining a variable phrase that holds a string value

print(phrase[3:6])#use print method for slicing and print its value

Output:

def

Explanation:

In the above code, a variable "phrase" is defined that holds a string value, and use a print method, inside the method, the variable is used as a list and use slicing.

It is a characteristic that enables you to access the series parts like strings, tuples, and lists. It also uses for modifying or removing objects in series, in the above slicing it starts from 3 and ends when it equal to the 6th letter, that's why it will print "def".

And timeline is the core of a project management software. The Gantt and Pert chart are totally based on the timeline. Software like Microsoft project use the timeline quite a lot, and you cannot survive without the knowledge  of the timeline in software project management.
