How many neutrons are in the nucleus of technetium-99m? How are radioactive isotopes formed? How to calculate nuclear binding energy per nucleon How does alpha decay release protons and neutrons? What is the ap
If an element has 12 protons and 17 neutrons, how many electrons does it have? How many protons, neutrons, and electrons does 108Ag+ have? How many protons and electrons are in the lead isotope with 124 neutrons? How many protons (p), neutrons (n) and electrons (e) are p...
For example: technetium-99 (which becomes stable after 2,120,000 years - after ten half-lives) can be reduced to material that becomes stable in just 43 days; and cesium-137 (which becomes stable after 302 years) can be reduced to products that are stable within 130 days. Patents have ...
Before discovering protons, neutrons and electrons, scientists tried to classify the elementsby arranging them in order of their atomic weights. ... Also, some elements were placed in groups with elements that were not similar to them. Who presented the law of octave? Law of octaves, in chemi...
? Assuming the atom is uncharged, how many electrons are present? Protons and Neutrons:Protons and neutrons constitute two sorts of subatomic particles. Protons are drawn towards a negative charge, as they constitute a positive charge. Neut...
How many electrons are contained in the ion 13 Carbon+? How many protons are present in the nucleus of any Technetium atom? How many neutrons are present in the nucleus of a Technetium-99 atom? The atomic number is 43 and it has a mass of 99. The atomic mass number of an ato...
How many neutrons are present in the nucleus of a Technetium-99 atom? The atomic number is 43 and it has a mass of 99. (a) How many atoms of helium gas fill a spherical balloon of diameter 31.0 cm at 19.0 degrees...
In nature, every element is divided into various isotopes, each of which is defined by the number of neutrons in its nucleus. Sometimes, the nucleus of an isotope has so many protons and neutrons that the isotope does not have the energy necessary to hold its nucleus together. When this ...
Atomic Number: The atomic number of an element represents the number of electrons or the number of protons in the element while the atomic mass represents the sum of neutrons and protons that exist in the element. Answer and Explanation:
(b) How do the isotopes of a given element differ? Isotopes: These elements have similarities in atomic number but different masses because they have a different numbers of neutrons. Due to this, the atom's charge will not be affected, but some different p...
