The one with atomic number 77, which is iridium.
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
The electrons farthest away from the nucleus are the valence electrons of an atom.
Helium atom has 2 electrons.
An atom with 2 electrons would be helium, an atom with 8 electrons would be oxygen, and an atom with 6 electrons would be carbon.
electronegativity
In neutral form, iridium should have 77 electrons. It also has 77 protons due to the fact that its atomic number is 77.
the element Ir has 77 electrons
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
1 atom of iridium has 77 electrons in total.
A nitrogen atom has seven electrons.
The electrons farthest away from the nucleus are the valence electrons of an atom.
Helium atom has 2 electrons.
There are 33 electrons in an Arsenic atom.
A single atom of Carbon has 6 electrons, with 4 in the outer shell which it will use to react
Yes, electrons do spin in an atom.
valence electrons
The outer electrons of an atom are called valence electrons.
