The diagram shows the electron configuration of an atom of an element for the electrons in the s and p orbitals. what is the group number of the element in the periodic table? a. 17 b. 16 c. 2 d. 1

A. 17

Explanation:

Periods and Groups are key to remember

Periods are horizontal rows while

Groups are vertical rows

There are 9 valence electrons within this configuration

The Electron Configuration for said diagram is 1s^2,2s^2,2p^5

Fluorine is the element that said diagram represents

The group in which Fluorine is in, is Group 17. More notably 7A.

Answer : The correct option is, (A) 17

Explanation:

Group : A column in the periodic table is known as group.

The common features about the elements of a same group is that the each groups has elements with the same number of valance electrons.

As we know that if the element belongs to s-block, its group number = Number of valence electrons (or outermost shell electrons).

As we know that if the element belongs to p- block then the group number = no. of valence electrons + 10

From the given diagram of electronic configuration of an atom we conclude that, there are 7 valence electrons present in their outermost shell. So,

Group number = Number of valence electrons + 10

Group number = 7 + 10 = 17

Hence, the group number of the element in the periodic table is, 17.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
