Which elements found in nature have mainly radioactive isotopes?
Some elements found in nature that mainly have radioactive isotopes include uranium, thorium, and potassium. These elements have naturally occurring radioactive isotopes that decay over time, releasing energy in the form of radiation.
Is erbium radioactive?
All erbium ordinarily found in nature is of stable isotopes. Like all other elements, erbium has synthetic radioactive isotopes.
How many valence electrons are found in an atom of magnesium?
Mg has 2 valence electrons.
How many valence electrons are found in an atom of each what element Helium?
Helium has 2 valence electrons.
Is neon radioactive?
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
Is xenon radioactive?
None of the isotopes of xenon ordinarily found in nature is radioactive. Like all elements, xenon has synthetic radioactive isotopes.
Why is silver radioactive?
Silver itself is not radioactive. However, certain isotopes of silver can be radioactive. For example, silver-108 and silver-110 are radioactive isotopes with long half-lives that can undergo radioactive decay. These isotopes are not commonly found in nature.
What are electrons found in an atoms outer shell called what?
The electrons in the outermost shell is called as valence electron. These electrons are free and they are involved in bonding reactions.
What valence electrons?
The electrons found in the outermost shell (or energy level) are known as the valence electrons.

Is erbium radioactive?
All erbium ordinarily found in nature is of stable isotopes. Like all other elements, erbium has synthetic radioactive isotopes.
How many valence electrons are found in a krypton atom?
A krypton atom has 8 valence electrons in the 4s and 4p orbitals.
How many valence electrons are found in an atom of magnesium?
Mg has 2 valence electrons.
How many valence electrons are found in calcium?
Calcium has 2 valence electrons. It is in group 2 of the periodic table, which means it has 2 electrons in its outermost energy level.
What are valence electrons and where can they be found?
Valence electrons are the outermost electrons in an atom that participate in chemical bonding. They are found in the highest energy level (shell) of an atom. The number of valence electrons can determine an element's reactivity and the types of chemical bonds it can form.
How many valence electrons are found in an atom of each what element Helium?
Helium has 2 valence electrons.
What is the maximum number of electrons that might be found in the valence shell?
The maximum number of electrons that can be found in the valence shell is 8. This is known as the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a full valence shell of 8 electrons.
