What element has a electron of 85?
The element with the atomic number 85 is Astatine (At). Astatine is a Radioactive Halogen in Group 17(7) of the Periodic Table. Astatine has 85 electrons in 6 shells with 7 electrons in the outer shell. Astatine is the third radioactive element on the Periodic Table.
What group does group one from the periodic table likes to reacts with?
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
What is the valence number of Barium?
Look on the periodic table of elements. Barium is in the 2nd column. All elements in the 2nd column have a charge (valence Number) of +2. The have 2 electrons in their outer shell.
How many outer shell electron does an atom of an element belonging to the halogen family have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
What charge does plutonium have when it forms an ion?
Ions with plutonium have valences between 3 and 7.
What is a technetium ions?
Technetium valences are between -1 and +7; the most usual valences are +3, +4 and +7.
Element bromine electrons outer shell?
Bromine has 7 electrons in its outer shell.

How many atoms are in the valance shell of 17 protons?
7. there is 17 electrons, 2 in the first shell, 8 in the second and 7 in the third
What is the valency of neptunium?
Neptunium has valences from +3 to +7.
What is the valency of americium?
Americium has valences between +2 and +7.
What group does group one from the periodic table likes to reacts with?
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
What is the valence number of Barium?
Look on the periodic table of elements. Barium is in the 2nd column. All elements in the 2nd column have a charge (valence Number) of +2. The have 2 electrons in their outer shell.
What element has the symbol At?
The element with the symbol At is Astatine. Astatine is a Group 17(7) Halogen and is radioactive. It has 85 electrons in 6 shells, with 7 electrons in the outer shell.
Why are Sodium and Chlorine not stable elements?
Sodium and Chlorine are chemically unstable due to the amount of electrons each has in the outer shells (also known as layers) of their atoms. Sodium has 11 electrons. First shell: 2 electrons Second shell: 8 electrons Third shell: 1 electron As the number of electrons in the last shell is not 8 and as the shell is not full Sodium is chemically unstable. Chlorine has 17 electrons. They are arranged like this: First shell: 2 electrons Second shell: 8 electrons Third shell: 7 electrons The number of electrons in the last shell is not 8, and the shell is not full, and thus, chlorine is chemically unstable. To give an example of a chemically stable element, Argon has 8 atoms in its last shell, which is why it is chemically stable and therefore does not react with any element.
What is the oxidation number of americium?
Americium has valences between 2 and 7.
How many protons does chlorine have in their inside thes hell?
There are 17 altogether . . . The first shell has 2 The second shell has . . . 8 And the third shell has . . . 7 I hope this has helped :) x
