What elements noble-gas configuration contains Xe?
The atomic number of xenon is 54 whereas the atomic number of the next noble gas, radon, is 86. So the elements with atomic number 55 to 86 will contain Xenon while writing the noble gas configuration. rhenium(Re) <3
What is the nearest noble gas to neon?
The nearest noble gas to neon is argon. Neon is located in Group 18 of the periodic table, and argon is the next element down in the same group. Neon has an atomic number of 10, while argon has an atomic number of 18.
What elements mass is 30 and a noble gas but not neon?
The element with a mass of 30 and is a noble gas, other than neon, is krypton (Kr). With an atomic number of 36, krypton has 36 protons in its nucleus and typically has 44 neutrons in its most common isotope, giving it an atomic mass near 84.
What atomic mass would you expect and ldquoekasilicon and to have Why?
Ekasilicon, or element 14, is the hypothetical element predicted to be the next heavier homolog of silicon (atomic number 14). Since silicon has an atomic mass of approximately 28.09 amu, ekasilicon would likely have an atomic mass slightly higher than that, possibly around 30-32 amu, due to the addition of protons and neutrons in its nucleus. This estimate is based on periodic trends and the expected increase in atomic mass with increasing atomic number.
How do you know which one is the atomic number?
The atomic number of an element represents the number of protons in the nucleus of an atom. It is typically located above the chemical symbol of the element in the periodic table. The atomic number determines the identity of an element and its position in the periodic table.
What is the possible atomic number of new element which resembles noble gases?
Noble gases with atomic numbers 2, 10, 18, 36, 54 and 86 are known. The next in the series will be element with atomic number 118.
What elements noble-gas configuration contains Xe?
The atomic number of xenon is 54 whereas the atomic number of the next noble gas, radon, is 86. So the elements with atomic number 55 to 86 will contain Xenon while writing the noble gas configuration. rhenium(Re) <3
What elements mass is 30 and a noble gas but not neon?
The element with a mass of 30 and is a noble gas, other than neon, is krypton (Kr). With an atomic number of 36, krypton has 36 protons in its nucleus and typically has 44 neutrons in its most common isotope, giving it an atomic mass near 84.

What element has a mass number of 21 and an atomic number of 10?
Sc, scandium (21), the first metal element in the 3d-block (transition elements); next to calcium (20).
Where do you fine out how many protons the atom has?
Look in the periodic table in school text books or revision guides - the number of protons in an atom is the same as the atomic number. In most periodic tables the atomic number is the subscript number next to the symbol of the element. The other number is the atomic mass - usually shown as the superscript number next to the symbol of the element. The atomic number is the smaller of the two numbers.
Why does an atomic number increase?
If you mean looking at the next element on the table then the mass would increase. However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight. Variations in Neutron count can cause differences in atomic weights.
How do you know which one is the atomic number?
The atomic number of an element represents the number of protons in the nucleus of an atom. It is typically located above the chemical symbol of the element in the periodic table. The atomic number determines the identity of an element and its position in the periodic table.
How can colliding lead and nickel atoms create an element assigned the atomic number of 110?
When the two elements collide or strike against each other, the atomic number of the nickel(Ni), which is 28, combines in with the atomic number of the lead(Pb),which is 82, causing the lead's atomic number to increase up to 110..BabyKay is the next Mariah Carey..lolxz
Argon atomic number?
It's element #15. Try Google next time.
Who discovered the atomic-number?
The atomic number was not discovered, as such. It's only when scientists realised that there were such things as atoms and the weights of them varied that they put them into some sort of order. So the lightest (hydrogen) is atomic number 1 and the next (helium) is 2, and so on.
Why is helium on the right side instead of being next to helium?
Helium is placed on the right side of the periodic table because it belongs to the noble gases group. Noble gases have similar chemical properties, hence they are grouped together on the right side of the periodic table. Helium is placed next to neon instead of itself due to the periodic table's structure, which is based on increasing atomic number.
