I am not positive what you mean by "core electrons" but:
57 (total) 7 (valence, outermost) 50 (non-valence, everyone but valence)
Carbon has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
The atomic number of Iodine is 53, and so one atom of Iodine has 53 protons. In order for the charge to be balanced, each atom of Iodine must also have 53 electrons.
this depends on what you mean the "core". there is a nucleus in an atom which is the very centre where the protons and neutrons are but the electrons spin around the nucleus in shells. the first shell has a maximum of 2 the second, a maximum of a 8 and so on.
it has 2 electrons i think you can tell by subtracting both numbers together
Barium has 56 eletrons56 electrons and protons.
53
An iodine atom has seven valence electrons.
sad
Iodine is a non metal element. There are 53 electrons in a single atom.
Seven
As an iodine atom has 53 electrons, an iodide ion has 54 electrons.
Iodine has 53 protons, and in a neutral atom, the number of electrons is equal to the number of protons. Therefore, iodine also has 53 electrons. This balance of protons and electrons ensures that the atom is electrically neutral.
The outer most electron shell of iodine atom contains 7 electrons.
There is no Iodone atom, there is however an Iodine atom that has seven valence electrons or seven electrons in outermost shell.
Germanium has 18 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
Iodine in its natural form is I2, two iodine atoms bonded with a single covalent bond. There are 6 non-bonded valance electrons on each atom, so there are 12 electrons in the electron-dot structure.
Carbon has 2 core electrons. Core electrons are the inner electrons of an atom that are not involved in chemical bonding.
