What has 17 protons and electrons?
chlorine atom
A chlorine atom has 17 protons, 18 neutrons, and 17 electrons.
What element has a charge of 17?
Table of Common Element Charges
| Number | Element | Charge |
|---|---|---|
| 17 | chlorine | 1- |
| 18 | argon | 0 |
| 19 | potassium | 1+ |
| 20 | calcium | 2+ |
Which element has 17 protons in the nucleus?
chlorine
An element with 17 protons will always be chlorine. However an element’s mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
Are there 17 electrons in chlorine?
In order to write the Chlorine electron configuration we first need to know the number of electrons for the Cl atom (there are 17 electrons). When we write the configuration we’ll put all 17 electrons in orbitals around the nucleus of the Chlorine atom.
How many valence electrons does chlorine atomic number 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.

What are the elements of 17th group?
The halogen elements are the six elements in Group 17 of the periodic table. Group 17 is the second column from the right in the periodic table and contains six elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (As), and tennessine (Ts).
What isotope has 17 neutrons?
Cl-37
Statement 1 : The isotope Cl-37 has 17 protons, 17 neutrons, and 17 electrons. Statement 2 : The atomic mass of chlorine is 35.43 amu.
What element has 17 protons and 7 valence electrons?
Chlorine
Chlorine has seven valence electrons. Chlorine has atomic number 17. The atomic number is the number of protons present in the nucleus of an atom. All the atoms of an element have same atomic number.
Which element contains 17 protons and 19 neutrons?
And the mass of protons and neutrons is considered to be equal. As the atom of chlorine has 19 neutrons, the mass number of chlorine is 17 + 19 = 36
What is the element with 17 protons?
If you see the periodic table, the 17th element will be the element having 17 protons. The 17th element of the periodic table is chlorine with symbol Cl.
What is an element with atomic number 17?
Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature. [35.446, 35.457] 35.4527 35.45
What is the total number of valence electrons in an atom?
The maximum number of valence electrons for an atom is eight. There are two lines of elements listed below the main table on the periodic chart, the lanthanides and actinides. All lanthanides belong in Period 6, Group 3. Actinides belong in Period 7, Group 3. These elements are known as inner transition metals.
