What is the electron configuration of 17?
The neutral atom chlorine (Z=17), for instance has 17 electrons. Therefore, its ground state electronic configuration can be written as 1s22s22p63s23p5.
How many electrons are in the atomic number 17?
17 electrons
So… for the element of CHLORINE, you already know that the atomic number tells you the number of electrons. That means there are 17 electrons in a chlorine atom.
What is the group configuration of the elements in group 17?
These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)….Elements.
| Halogen | Configuration |
|---|---|
| Fluorine | 1s2 2s2 2p5 |
| Chlorine | [Ne]3s2 3p5 |
| Bromine | [Ar]3d10 4s2 4p5 |
| Iodine | [Kr]4d10 5s2 5p5 |
Which of the following is the electron configuration for chlorine with 17 electrons?
Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.

| 18 | Ar | Argon |
| 19 | K | Potassium |
| 20 | Ca | Calcium |
Which period and group the element belongs 17?
Since the element is in group 17. So, it is a halogen. Halogens start from the second period. There is chlorine in the third period.
Which element has an atomic number of 17?
What is the electronic configuration of a chlorine atom chlorine has an atomic number of 17?
The atomic number of Chlorine(Cl) is 17 and the electronic configuration is; 2,8,7 with seven electrons in the valence shell.
How many valence electrons does group 17 have?
seven valence electrons
A: An atom of a group 17 element such as chlorine has seven valence electrons. It is “eager” to gain an extra electron to fill its outer energy level and gain stability. Group 16 elements with six valence electrons are almost as reactive for the same reason.
What is the valency of group 17 elements?
7 electrons
All the Group 17 elements have the same outer electronic configuration, and that is ns2 np5, where ‘n’ stands for the shell number. As can be seen from the electronic configuration, the outermost shell of the halogen atoms have 7 electrons; thus, their valency is 7.
How many neutrons does chlorine 17 have?
18 neutrons
Chlorine has an atomic number of 17 and an atomic mass of 35.45, meaning that an atom of chlorine consists of 17 protons, 17 electrons, and 18 neutrons.
Which energy level would accommodate the 17th electron?
Answer: As we know the formula for knowing the number of electrons in a shell it is 2n^2. Therefore the 17th electron will be accommodated in the third energy shell.
What is 17 on the periodic table?
Chlorine – Element information, properties and uses | Periodic Table.
Which group does the element with atomic number 17 belongs to *?
To which group and period does it belong to? 2,8,7 is the electronic configuration of the element whose atomic number is 17. As it has 7 valence electrons. So Its belongs to 17th group and 3rd period.
What is the period number of 17?
1 Answer. It belongs to 17th Group and 3rd Period.
Is there a atomic number 17?
Chlorine (Cl) – Atomic Number 17.
What element has an atomic number of 17?
What atom has 17 protons and 18 neutrons?
chlorine atom
Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei.
What is group 17 on the periodic table called?
halogen
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
What is the name of Group 17?
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
What is the electron configuration if the atomic number is 17?
The electron configuration is 1s22s22p63s23p5. If the atomic number is 17, there must be 17 protons and 17 electrons. Starting from the lowest level, we add electrons to each higher level until we have reached 17 electrons. The electron configuration becomes 1s22s22p63s23p5.
What is electron configuration?
Let us learn more about the electronic configuration along with some awesome worksheets and orbital diagrams in this article. The electron configuration of an element is a standard representation of its electron arrangement in the orbitals of its atom.
How do elements in the group 17 share electrons?
All the Group 17 elements are molecules containing two atoms. By sharing electrons in a covalent bond full outer electron shells are achieved. The atoms of each element gain more shells and increase in size going down the group.
Which electron configuration is the most stable?
The ground state electron configuration is the most stable one that means it possess stable arrangement of electrons. The other name for ground state is vacuum state. Excited State: The highest possible energy levels among all the atomic orbitals around the nucleusrefers to excited state.
