Iodine 125 (I-125) is the isotope of iodine whose nucleus consists of 53 protons and 72 neutrons.

What is the correct atomic symbol for an atom with 53 protons 54 electrons and 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).

What element has 53 electrons and 73 neutrons?

Krypton has 36 protons and 47 neutrons. Iodine has 53 protons and 73 neutrons.

What element has 53 protons 77 neutrons and 54 electrons?

I (iodine) atoms (atomic number 53) have 53 protons and 53 electrons. I– (iodide) ions have 53 protons and 54 electrons. The composition of the nucleus for both cations and anions is the same as the corresponding atom. Thus the number of protons and neutrons is the same.

What is the net charge of an iodine ion containing 53 protons 74 neutrons and 54 electrons?

−1⋅6×10−19c.

What element has 53 number of protons?

Iodine is element number 53. Iodine has 53 protons and 53 electrons (because it has no charge the number of protons equals the number of electrons). Iodine-131 has 131 protons and neutrons. Iodine-131 has 131 minus 53 protons = 78 neutrons.

What has the atomic number 53?

Iodine is a chemical element with symbol I and atomic number 53. Classified as a halogen, Iodine is a solid at room temperature.

How many neutrons are in CR 53?

Chromium 53: The atomic number Z = 24, so there are 24 protons and 24 electrons. Number of neutrons = A – Z = 53 – 24 = 29.

What isotope has 53 protons and 78 neutrons?

A less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons). With “too many” neutrons in its nucleus, it is unstable and radioactive, with a half-life of eight days.

What has 53 electrons and 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 electron energy levels does an atom of iodine atomic number 53 have?

Iodine has 7 valence electrons and 46 core electrons for a total of 53 , the atomic number.

How many protons does an ion with 74 electrons and a charge of +4 contain?
