What else can I help you with?
What are the ten elements in thre periodic table that are radioactive?
all elements after uranium (atomic number 92) are radioactive.
What is the first radioactive element number?
Of elements that have no stable isotopes, technetium has the lowest atomic number, which is 43.
What element continue to decay until they finally become stable?
All elements above the atomic number of 83 are radioactive, but two elements that are under it are also radioactive. They are technetium (atomic number 43) and promethium (atomic number 61). Radioactive elements are elements that decay until stable. =)
What are the radioactive elements with atomic number from 90 to 103 in the periodic table called?
The elements with atomic numbers from 90 to 103 are called actinides. These elements are known for being radioactive and having partially filled 5f orbital. They include well-known elements like uranium, plutonium, and americium.
By how many units do that atomic numbers of these two elements differ?
To determine how many units the atomic numbers of two elements differ, you need to know the atomic numbers of both elements. The atomic number is defined as the number of protons in an atom's nucleus. Once you have the atomic numbers, you can simply subtract one from the other to find the difference in units. If you provide the names or symbols of the two elements, I can give you the specific difference.

What are the radioactive elements with atomic number from 90 to 103 called?
The Actinides.
Can atoms of the same element differ in atomic number?
no. elements are defined by their atomic number (the number of protons).
Radioactive elements comprise a majority?
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
What element continue to decay until they finally become stable?
All elements above the atomic number of 83 are radioactive, but two elements that are under it are also radioactive. They are technetium (atomic number 43) and promethium (atomic number 61). Radioactive elements are elements that decay until stable. =)
Which alkaline earth metal is radioactive?
Radium. Elements with an atomic number greater than 83 are always radioactive.
How are the elements with atomic numbers 43 and 61 are unique?
The element with atomic numbers 43 (Technetium) and 61 (Promethium) are unique because they are the only radioactive elements before the start of the bulk of the radioactive elements. The bulk of the radioactive elements begins at atomic number 84 (Polonium). These are significant as they aren't primordial and are only found due to radioactive decay.
Which elements in the peridoic table are radioactive elements?
All elements from atomic number 84 (Polonium - Po) and onwards are radioactive, although ones that have not been observed cannot be confirmed.
What family of metals are all radioactive?
Actinoids, and generally all the elements from polonium (atomic number 84) to ununoctium (atomic number 118).
What are the radioactive elements with atomic number from 90 to 103 in the periodic table called?
The elements with atomic numbers from 90 to 103 are called actinides. These elements are known for being radioactive and having partially filled 5f orbital. They include well-known elements like uranium, plutonium, and americium.
All isotopes of this element are radioactive?
Radioactive Elements (38) These elements are radioactive. They either have no stable naturally occurring isotope, or else are entirely artificial (all artificial elements have no stable isotopes). by Andrew Moore
