What is the Atomic number for neutral unionized atoms?
The atomic number refers to the number of protons within an atom's nucleus and defines which element the atom is. And an ion is an atom with some level of positive or negative charge as a result of losing or gaining electrons, so ionisation has no effect on the atomic number (an ion of copper is still copper) and a negligable effect on the atomic mass - since electrons are relatively very light.The only way the atomic number can change is through nuclear fission (elements decaying into isotopes and lower elements) or nuclear fusion (creating higher elements).As such this question makes no sense.
5 why is Gypsum is a 2 on Mohs hardness scale while topaz is an 8 Can gypsum scratch topaz?
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to scratch topaz.
What does it means if a solution has a pH of 3 12 2 7 or 9?
On the pH scale, lower numbers are more acidic, higher numbers are more basic (alkaline). 1 is the strongest acid, 14 is the strongest base, 7 is neutral.
What is a sanitizing temperature?
171 degrees Fahrenheit or higher is a sanitizing temperature. Safe sanitization uses either heat or chemicals to reduce the numbers of disease causing organisms.
A physical property that tells you how hot or cold matter is?
The physical property that tells you how hot or cold matter is, we call temperature. Temperature consists of random motion on the atomic or molecular scale. Faster moving particles have higher temperatures.
How were all the elements with atomic numbers higher that 42?
These elements are in the periods 5 to 7.
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.
How are elements with atomic numbers higher than 92 created?
Isotopes were then explained as elements with the same number of protons, --- In the 1950s, the development of improved particle accelerators and --- All known isotopes of elements with atomic numbers greater than 82 are radioactive.Evaa_I_WILL_H3LP_YOU
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.
