How are mass number and atomic number of an element related?
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
What element is in group 1 and has a higher atomic number than chlorine but a lower atomic number than chlorine?
It is K, or Potassium, which atomic number is 19, which is greater than 17 and less than 35, and in group 1 of the periodic table, which is the alkali metals.
Why is the atomic number included in the periodic table?
Presumably because atomic number is the fundamental characteristic for organizing the periodic table itself. Every element in the interior of a period of the periodic table has an atomic number greater by 1 than its neighbor to the left and less by 1 than its neighbor to the right; every element (except hydrogen) at the left end of a periodic table period has an atomic number greater by one than the rightmost member of the preceding period; and every element at the right end of a periodic table periodic has an atomic number less by 1 than the leftmost element in the succeeding period, if such a succeeding period exists.
What is the first element with an atomic mass greater than 100?
Unnilunium
What element has an atomic number greater than 32?
Gold is one.
Which element has an atomic number 6 times greater than that of Beryllium?
Chromium (Cr), which has an atmoic number of 24. Beryllium has an atomic number of 4, so 4*6=24, which is Chromium.
What element in group one has a higher atomic number than chlorine but lower atomic number than bromine?
The element in group one with a higher atomic number than chlorine but lower atomic number than bromine is iodine. Its atomic number is 53, which is greater than chlorine's atomic number of 17 but less than bromine's atomic number of 35.
What element has an atomic number that is six times greater than element beryllium?
The atomic number of beryllium is 4. The required element should have the atomic number 4x6=24. The corresponding element is Vanadium (V).Atomic number of Beryllium is 4. Six times of it is 24. Chromium has an atomic number of 24.
What element has a gram atomic mass that is greater than the gram atomic mass of the element with an atomic number higher by one unit?
Both argon and cobalt have this characteristic.
Which element is thousands time greater than uranium?
It is not clear what "greater" means. In terms of atomic number (number of protons in the nucleus) there is not even an element which is twice as great.
Any element with an atomic number greater than 92 is?
An element with an atomic number greater than 92 is considered a transuranium element. These elements are artificially created in a laboratory and are generally unstable, undergoing radioactive decay. Examples include neptunium, plutonium, and americium.
How are mass number and atomic number of an element related?
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
What is the first trans uranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
What element is in group 1 and has a higher atomic number than chlorine but a lower atomic number than bromine?
It is K, or Potassium, which atomic number is 19, which is greater than 17 and less than 35, and in group 1 of the periodic table, which is the alkali metals.
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
What element has an atomic mass greater than 75 but less than 79?
Element 34, Selenium, has an atomic mass of about 78.96.
