1. The atomic number is equivalent to the number of protons in the atomic nucleus of a chemical element. The number of protons is identical for all the isotopes of an element.

2. The mass number is the sum of protons and neutrons in the atomic nucleus of an isotope.

Are there any elements with no stable forms?

Many of the elements with higher atomic numbers have no stable form yet discovered, ex: ununoctium.


What is another name for the newly formed isotope?

There isn't another name for isotopes. What it means is Any two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. There are 275 isotopes of the 81 stable elements, in addition to over 800 radioactive isotopic forms.


What are alternate forms of elements with differing neutron numbers?

Isotopes are alternate forms of elements with differing neutron numbers. Isotopes have the same number of protons (and thus the same atomic number), but different numbers of neutrons, leading to variations in atomic mass. Some isotopes are stable, while others are radioactive and undergo decay.


What is a radioactive reaction?

A radioactive reaction is a process in which unstable atomic nuclei decay into more stable forms by emitting particles such as alpha or beta particles, along with gamma rays. This decay releases energy and transforms the original element into a different element or isotope. These reactions are used in various fields such as medicine, industry, and energy production.


Technetium in brackets?

Any time you see the atomic mass of an element in brackets on the periodic chart, that number represents the mass number of the longest-lived or best-known isotope of that element. In other words there is no stable isotope, i.e. all forms of it are radioactive.

what is isotop?

each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element. Example : carbon12 Isotopes are different versions of an element with varying numbers of neutrons in their nucleus. They have the same number of protons but different numbers of neutrons. These variations in neutrons give each isotope a different atomic mass. Isotopes can be stable or radioactive, and they play a crucial role in various scientific fields like medicine, archaeology, and environmental studies.


When a radioactive nucleus decays and forms a new nucleus is the new nucleus always radioactive?

No. A stable nucleus can form. If the new nucleus is radioactive, then it will contiue to decay until a non radioactive nucleus is attained.


Is phosphorus stable or unstable?

Phosphorus is stable in its common forms, such as white phosphorus and red phosphorus. However, there are unstable isotopes of phosphorus that are radioactive and undergo decay.

A charged atom that forms when the numbers of electrons and protons are not equal?

atomic number


How atomic structure forms a bond?

It depends on the atomic number. For example some atomic numbers create oxygen and others create metal such as zinc.


Are there any other isotopes of xenon?

Xenon has eight stable naturally occuring isotopes. Besides these stable forms, there are over 40 unstable isotopes that have been studied.


Does alpha beta and gamma radiation form as the result of chemical reactions?

No, alpha, beta, and gamma radiation are forms of nuclear radiation, not chemical reactions. They result from the decay of unstable atomic nuclei in a process called radioactive decay, where atoms emit particles or energy to become more stable.
