How many total electrons are in iodine?
A neutral iodine atom will have a total of 53 electrons around its nucleus. Out of these 53 electrons, some are known as valence electrons while others are known as core electrons.
What is the number of electrons in a neutral atom?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
How many valence electrons does a neutral atom of iodine I have?
seven valence electrons
Iodine has seven valence electrons. Valence electrons of an atom are located in the outermost shell of the atom and participate in bonding.
How can you predict the number of electrons in a neutral atom?
Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.

What is the atomic number for iodine?
53Iodine / Atomic number
What is neutral atom?
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
How many electrons are in a neutral atom of boron?
This means that an atom of hydrogen has one proton, and, if it’s neutral, one electron as well. Gold, on the other hand, has an atomic number of 79, which means that an atom of gold has 79 protons, and, if it’s neutral, 79 electrons as well….Atomic Number.
|Atomic Number (Z)||5|
Can iodine have 10 valence electrons?
So, iodine can use all of these electrons in chemical bonding: 2 in the 5s, 5 in the 5p and up to 10 in the 4d, although it only needs to use 4 of its 4d electrons to do the bonding in this molecule.
What is the rule for making a neutral atom?
Explain you answer. The number of electrons and protons should be equal in a neutral atom. Because each electron has a -1 charge, and each proton a +1 charge, the number of each must be the same for the net charge to equal zero. Not all atoms are neutral.
How does iodine occur in nature?
Iodine can be found naturally in air, water and soil. The most important sources of natural iodine are the oceans. About 400.000 tonnes of iodine escape from the oceans every year as iodide in sea spray or as iodide, hydrichloric acid and methyl iodide, produced by marine organisms.
