Which element in each pair has atoms with a larger atomic radius strontium or magnesium?
Strontium
How can you determine whether one number is a factor of another?
Divide the smaller into the larger. If the quotient is an integer, the smaller is a factor of the larger.
Is Africa larger or smaller than Asia?
No single continent will ever be larger than Asia because Asia is the largest continent in the world. Africa is a single continent therefore, it is smaller than Asia.
Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.
What is larger than the ocean?
That Is a difficult question because what are you asking about? Most planets in our solar system are larger than all oceans combined as well as most stars. I think all the continents combined is smaller that the oceans combined.
Barium element is larger or smaller than caesium?
Barium is smaller than caesium. Different elements have different atomic radii, with caesium having a larger atomic radius compared to barium.
Is barium smaller than aluminum?
Barium (137.327) is larger than aluminum (24.305)
Which element would be most reactive be sr or ba?
Barium (Ba) would be more reactive than strontium (Sr) because barium is located further down the Group 2 elements in the periodic table. As you move down the Group, the reactivity of the elements tends to increase due to the larger atomic size and lower ionization energy, making barium more reactive than strontium.
Where is the lowest electronegativity barium calcium magnesium or strontium?
Both are ions and we should consider the ionic radius, not the atomic radius. Rubidium ion (Rb+) will have a larger IONIC radius than strontium ion (Sr2+). Both ions have the same electronic configuration. But strontium ion has more number of protons in the nucleus. Hence it will have greater force of attraction between the nucleus and the valence electrons, resulting in smaller size.
Element M reacts with chlorine to for a compound MCl2 Element M is more reactive than magnesium and has a smaller radius than barium the element is?
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
Why is barium more reactive than storntium?
Barium is more reactive than strontium primarily due to its larger atomic size and lower ionization energy. As you move down the alkaline earth metal group in the periodic table, the atomic radius increases, making it easier for the outer electrons to be removed. Barium's additional electron shell reduces the effective nuclear charge experienced by its outermost electron, facilitating its reactivity compared to strontium. Additionally, the weaker attraction between the nucleus and the outer electrons in barium enhances its tendency to lose electrons and react.
Is barium larger than aluminum yes or no?
a general answer is that if it is a cation the ion is smaller than the atom due to loosing one or more electrons which would decrease the size of the radius anions are larger because they are gaining more electrons and electron electron repulsion is greater which spreads the anion apart
Which of the alkaline earth metals is the largest?
Barium is the largest alkaline earth metal due to its larger atomic size compared to the other alkaline earth metals like magnesium, calcium, strontium, and radium.
Why only strontium and barium forms peroxide?
Strontium and barium are able to form peroxides due to their relatively low ionization energies and the presence of vacant d orbitals in their valence electron configurations. This allows them to readily accept additional electrons to form the peroxide ion (O2^2-). Additionally, the larger size of strontium and barium ions compared to other alkaline earth metals provides more space for the peroxide ion to be accommodated, making them more likely to form stable peroxides.
Which element in each pair has atoms with a larger atomic radius strontium or magnesium?
Strontium
Is strontium larger than a calcium atom?
Yes, strontium is larger than a calcium atom. Strontium has a higher atomic number (38) compared to calcium (20), which means it has more electron shells. This additional shell increases the size of the strontium atom, resulting in a larger atomic radius than that of calcium.
Why does beryllium chloride has more covalent character than barium chloride?
Beryllium chloride has more covalent character than barium chloride because beryllium is a smaller cation with a higher charge density, leading to stronger interactions with the chloride anions. This results in a more polar covalent bond in beryllium chloride compared to the more ionic bond in barium chloride due to the larger size and lower charge density of barium.
