How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
Is carbon heavy?
Carbon is considered a light element in terms of atomic weight, as it has an atomic number of 6 and an atomic mass of approximately 12.01 atomic mass units. In comparison to elements like uranium or lead, which have much higher atomic numbers and masses, carbon is relatively light. However, in everyday language, we may refer to carbon as "heavy" when discussing its presence in molecules or compounds due to its ability to form strong bonds with other elements.
What does it mean when something is referred to as a heavier element?
A heavy element is an element that based on the amount of metal that is in the element. Some can base the description of a heavier metal on the number of atoms but it is the amount of metal in the element.
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
How were all the elements with atomic numbers higher that 42?
These elements are in the periods 5 to 7.
How were all the elements with atomic numbers higher than 92 created?
Elements that follow uranium are made or synthesized when nuclear particles are forced to crash into one and other.
Why do elements of even atomic numbers are more abundant than that of odd numbers?
Elements with even atomic numbers are more abundant than those with odd atomic numbers because of nuclear stability. Elements with even atomic numbers have equal numbers of protons and neutrons, resulting in more stable nuclei due to pairing effects. This stability makes it easier for elements with even atomic numbers to be formed through various nuclear processes, leading to their higher abundance compared to elements with odd atomic numbers.
Chemical elements with atomic numbers greater than that of uranium are called?
Transuranium elements. They typically have atomic numbers higher than 92 (uranium's atomic number) and are all artificially produced through nuclear reactions.
What does elements with a higher atomic number than uranium have?
Elements with a higher atomic number than uranium belong to the transuranium elements, which are all man-made and generally unstable due to their high atomic numbers. These elements typically undergo radioactive decay, leading to the formation of lighter elements.
Why are the elements at the bottom of the series discovered before the elements on the top?
Elements at the bottom of the periodic table were discovered later because they have higher atomic numbers, indicating they have more protons in their nucleus. Historically, elements with lower atomic numbers were easier to study and discover due to their simpler properties and availability in nature. As technology advanced, scientists were able to synthesize and discover elements with higher atomic numbers, leading to the discovery of elements at the bottom of the periodic table.
How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
Why are elements with atomic numbers higher than 92 referred to as transuranium elements?
Elements with atomic numbers higher than 92 are referred to as transuranium elements because they are synthesized artificially by nuclear reactions and do not occur naturally in significant quantities on Earth. They generally have unstable nuclei and are radioactive, making them distinct from the naturally occurring elements in the periodic table.
Are actinoids all transuranium elements?
No, actinoids are a group of elements that include both transuranium elements (elements with atomic number greater than 92) and non-transuranium elements. Transuranium elements are specifically those that have atomic numbers higher than uranium (92).
What is the element for 5s2 4d10?
It is cadmium (48). However, all the elements with higher atomic numbers also have 5s2 4d10.
Are elements with an atomic number higher than 92 created in an particle accelarator?
maybe not or maybe so
How is the element's atomic number related to its posititon in the periodic table?
The periodic table is arranged in order of increasing atomic number, which is the number of protons in the nucleus of each atom. Generally speaking, the elements with low atomic numbers are toward the top and the ones with higher atomic numbers are toward the bottom.
