The covalent radius of francium is 260 pm.
The covalent radius of hydrogen is 31 pm.
Fr (Francium) has a larger atomic radius than F (Fluorine) because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of the alkali metal group while Fluorine is at the top of the halogen group.
It is not hydrogen so it must be nitrogen and bromine since it has a higher atomic radius.
The alkali metal with 76 fewer electrons than francium is lithium. Francium has 87 electrons, so lithium, which has 3 electrons, has 76 fewer electrons than francium.
Atomic (covalent) radius of hydrogen is 31 pm. Atomic (covalent) radius of gold is 136 pm.
Yes, a molecule of oxygen (O2) is larger than a molecule of hydrogen (H2) because an oxygen atom has a larger atomic radius and can form stronger bonds with other atoms, resulting in a larger molecule size.
The atomic size of francium is of course greater.
A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.
No, francium is larger than hydrogen. Francium is a much heavier element located at the bottom of the periodic table, whereas hydrogen is the lightest element. Size of an atom generally increases as you move down a group in the periodic table.
The francium atom is larger.
A francium atom (Fr) is larger than a hydrogen atom (H) due to the increase in number of protons and electrons, resulting in larger atomic size. Francium has more electron shells compared to hydrogen, leading to a greater atomic radius.
Francium has a larger atomic radius than sodium. Francium is located in the last group of the periodic table, so it has more electron shells than sodium, which results in a larger atomic radius.
Hydrogen and francium can combine to form a compound with the formula HFr, which stands for hydrogen francium. This compound would be highly unstable and reactive due to the extremely high reactivity of francium. Francium is a rare and radioactive element that is highly unstable and difficult to handle, making it unlikely to form stable compounds with hydrogen.
No, francium is more active than sodium. Francium is located in the Group 1 of the periodic table, making it the most reactive alkali metal due to its higher atomic number and larger atomic radius compared to sodium.
When francium and hydrogen combine, they form francium hydride (FrH), a compound where francium acts as a cation and hydrogen as an anion. Francium is extremely rare and radioactive, making it difficult to study its chemical properties in detail. The compound would likely be highly unstable due to francium's extreme reactivity.
Francium is softer than sodium. This is because as you move down the alkali metal group in the periodic table, the atoms get larger, making the metallic bonding weaker and resulting in softer metals.
Francium would react with water by this equation: 2Fr + 2H2O -->2FrOH + H2 The products here are francium hydroxide and hydrogen gas. However, it would be impossible to gather enough francium to demonstrate this reaction.
Carbon-hydrogen bonds are longer than hydrogen-hydrogen bonds because carbon has a larger atomic radius than hydrogen. The larger atomic radius of carbon results in a greater distance between the carbon and hydrogen atoms, leading to a longer bond length.
