How many neutrons and electrons are in iodine?
Iodine has 53 protons, 53 electrons, and 74 neutrons.
Does iodine have 74 neutrons?
The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74).

How many electrons are there in iodine?
53 electronsUsing our example, iodine, again, we see on the periodic table that its atomic number is 53 (meaning it contains 53 electrons in its neutral state).
How do u find neutrons?
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
What has 72 neutrons and 51 protons?
Antimony is a chemical element with symbol Sb and atomic number 51. Classified as a metalloid, Antimony is a solid at room temperature.
What atom has 131 neutrons?
Iodine-131Iodine-131 is a radioactive, or unstable, isotope of iodine. It is frequently used in medicine to detect the presence of thyroid cancer.

What is the electrons of iodine-131?
General Chemistry With Qualitative Analysis The mass number of ¹³¹I is 131 and the atomic number is 53. The atomic number of ¹³¹I is equal to the number of protons or the number of electrons. Thus, in the neutral state, the number of electrons present in iodine-131 is 53.
What element has 2 protons 2 neutrons?
heliumA helium nucleus has two protons and two neutrons.
Can iodine hold 12 electrons?
Iodine is below Period Two on the periodic table so it can have an expanded octet (hold more than eight valence electrons). In the Lewis structure for IF5 you'll need to put a total of 12 valence electrons on the Iodine atom in order to draw the Lewis structure.
What is the iodine atom that has 72 neutrons?
Iodine 125Iodine 125 (I-125) is the isotope of iodine whose nucleus consists of 53 protons and 72 neutrons.
How many neutrons are in as 74?
Tungsten has an atomic number of 74. Thus, there are 74 protons/electrons in the nucleus of a Tungsten atom. With an atomic mass of 183.84, tungsten holds 110 neutrons in the nucleus of its atom. Tungsten has the chemical symbol of W because its German name is wolfram.

What isotope has 74 protons?
tungstenThere are five different stable isotopes of tungsten containing 108, 110, 106, 109, and 112 neutrons. The average of these isotopes is 109. Adding the number of protons (74) yields tungsten's atomic number of 183. Tungsten contains exactly 74 protons in its nuclear makeup.
How many protons are in iodine?
Iodine is a chemical element with atomic number 53which means there are 53 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
How many electrons are in an iodine atom?
Therefore, the number of electrons in neutral atom of Iodine is 53. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
How do neutrons stabilize the nucleus?
Neutrons stabilize the nucleus, because they attract each other and protons , which helps offset the electrical repulsion between protons. As a result, as the number of protons increases, an increasing ratio of neutrons to protons is needed to form a stable nucleus. If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoes radioactive decay. Unstable isotopes decay through various radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture. Many other rare types of decay, such as spontaneous fission or neutron emission are known. It should be noted that all of these decay pathways may be accompanied by the subsequent emission of gamma radiation. Pure alpha or beta decays are very rare.
What are the two forces that make up the nucleus?
Atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force, while protons repel each other via the electric force due to their positive charge. These two forces compete, leading to various stability of nuclei. There are only certain combinations of neutrons and protons, which forms stable nuclei.
What is the mass of a proton?
It has a positive electric charge (+1e) and a rest mass equal to 1.67262 × 10−27 kg (938.272 MeV/c2) — marginally lighter than that of the neutron but nearly 1836 times greater than that of the electron. The proton has a mean square radius of about 0.87 × 10−15 m, or 0.87 fm, and it is a spin – ½ fermion.
What is the number of neutrons in an atom?
The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.
What is the periodic table?
The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers , electron configurations, and chemical properties. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements.
