Elements atomic radii increase in size as they run down the columns of the Periodic Table or across the periodic table from right to left. So, Al is larger than Cl. XP
What else can I help you with?
Why is the most stable conformational isomer of cis-1-bromo-2-chlorocyclohexane bromine equatorial and chlorine axial instead of bromine axial and chlorine equatorial?
The most stable conformation has the larger bromine atom in the equatorial position to reduce steric hindrance caused by its size. Placing the smaller chlorine atom in the axial position minimizes the overall energy of the molecule due to the difference in size between bromine and chlorine. This arrangement follows the principles of minimizing steric hindrance and maximizing stability.
Does chlorine atom has a smaller radius than chlorine ion?
Yes, considerably so. In general, positive ions are smaller than their neutral atoms, and negative ions are larger than their neutral atoms.
Is nitrogen bigger than oxygen?
They both have the same amount. NO2 (Nitrogen Dioxide) has one Nitrogen atom. NO (Nitrogen Monoxide) also has one Nitrogen atom. However, nitrogen monoxide has a higher % nitrogen in the molecule both by mole % and weight %.
S na cl mg witch one is largest?
Magnesium (Mg) is the largest atom among sulfur (S), sodium (Na), chlorine (Cl), and magnesium (Mg). This is because the size of an atom increases as you move down a group in the periodic table. Magnesium is located below the other elements in the periodic table, making it the largest atom among these options.
Which is More reactive chlorine or bromine?
Chlorine is more reactive than bromine. This is because chlorine has a higher electronegativity and smaller atomic size than bromine, allowing it to more readily undergo chemical reactions.
Is a chlorine atom or chlorine ion bigger?
A sulfur atom is larger than an oxygen atom.
What is the element size of bromine?
Its atom size is bigger than Chlorine but smaller than Iodine
What is bigger a chlorine atom or a chlorine ion?
A chloride ion is slightly larger than a chlorine atom, because in an ion there is one more electron than proton, allowing the electron shells to expand slightly. In a chlorine atom, the number of electrons and protons is the same.
Why can't chlorine form a hydrogen bond if it's electron negativity is equal to the nitrogen?
Size of Cl atom is bigger than size of N atom.Electronegativity difference is .12 which is negligible.
How would you arrange these elements in order of decreasing atomic size sulfur chlorine aluminum and sodium?
Sodium > Aluminum > Chlorine > Sulfur. Atomic size generally increases as you move down a group on the periodic table and decreases as you move across a period from left to right. Sodium is in the same period as chlorine but is a metal, so it has a larger atomic size. Aluminum is in the same period as sulfur but is a metal, so it has a larger atomic size. Chlorine is a non-metal and smaller than both aluminum and sodium. Sulfur is a non-metal and the smallest among the four elements listed.
Why the chlorine does not form hydrogen bond as the nitrogen do in spite the chlorine is more electronegative than nitrogen?
Hydrogen bonding occurs between hydrogen and a highly electronegative atom such as nitrogen, oxygen, or fluorine. Chlorine is less electronegative than these elements, so it is not able to form hydrogen bonds with hydrogen. In hydrogen bonding, the hydrogen atom must be covalently bonded to a highly electronegative atom.
Which element is bigger carbon or chlorine?
Chlorine is larger than carbon because chlorine has more electrons and energy levels, resulting in a larger atomic size.
Why is the most stable conformational isomer of cis-1-bromo-2-chlorocyclohexane bromine equatorial and chlorine axial instead of bromine axial and chlorine equatorial?
The most stable conformation has the larger bromine atom in the equatorial position to reduce steric hindrance caused by its size. Placing the smaller chlorine atom in the axial position minimizes the overall energy of the molecule due to the difference in size between bromine and chlorine. This arrangement follows the principles of minimizing steric hindrance and maximizing stability.
Why is chloride ion bigger than chlorine atom?
A thorough explanation requires quantum calculations, but as an approximation: A chloride ion is bigger than a chlorine atom because the ion contains an additional electron, but the positive charge of the nucleus is not changed from that of the atom. As a result, the average electrostatic force between the nucleus and each electron is slighter weaker in the ion, so that its electrons equilibrate with a larger average distance from the nucleus than in the atom. (The external dimension of either an atom or an ion is determined by the size of its electron cloud since the nucleus is too far inside the electron cloud to affect external dimension.)
How does the size of an aluminum atom change when it becomes an ion with a charge of 3 plus?
The outermost (3rd) shell of aluminium is occupied with 3 electrons will gave away 3 electron away as it forms an ion, hence the outermost shell which was occupied by those 3 electrons gone, thus the size of aluminium atom decrease.Added:Above that there are 13 proton charges (3 extra) to attract more the remaining 10 electrons, so they'll stay closer to the nucleus.Hence all positively charged ions are smaller than their respective neutral atoms.The reversed is true for negative ions: Chloride (Cl-) is bigger compared to Chlorine.(For spelling issue on aluminIUm i.s.o. aluminUm cf. Discussion-page)
Is a model of a atom the same size as a real atom?
No. A model is a bigger or smaller version of the actual thing, in this case the model is bigger than the real thing.
What is smaller chlorine sulfur silicon or phosphorus?
Chlorine is the smallest of those elements, followed by sulfur, silicon, and phosphorus. The size of an atom is determined by the number of protons and electrons it has, with more protons making the atom smaller.
