A smaller atomic radius for beryllium would result from an increased positive charge in its nucleus, leading to a stronger attraction between the nucleus and the valence electrons. This increased attraction pulls the electron cloud closer to the nucleus, resulting in a smaller atomic radius.
What else can I help you with?
Which alkali earth metal has the smallest atomic radius?
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
What is the difference between the atomic radii of sodium (Na) and potassium (K)?
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.
How does fluorines atomic radius compare to oxygen radius and chlorines radius?
Fluorine has the smallest atomic radius among fluorine, oxygen, and chlorine. Oxygen has a larger atomic radius than fluorine but smaller than chlorine. Chlorine has the largest atomic radius among the three elements.
What is smaller than the atomic radius of beryllium?
Generally, any element with a lower atomic number.
What is smaller than the atomic radius of beryllium (Be)?
Generally, any element with a lower atomic number.
Does beryllium or barium have a bigger atomic radius?
Barium has a larger atomic radius than beryllium. This is because as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of energy levels. Barium is located lower in the periodic table than beryllium, leading to a larger atomic radius.
Which alkali earth metal has the smallest atomic radius?
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
How does the size of a beryllium atom compare to one of oxygen?
The empirically atomic radius of beryllium (105 pm) is higher than the empirically atomic radius ofoxygen (60 pm).
What elements has a smaller atomic radius than strontium?
Elements with a smaller atomic radius than strontium include beryllium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, and argon. Generally, atomic radius decreases across a period from left to right due to increased nuclear charge, which pulls electrons closer to the nucleus. Additionally, atomic radius increases down a group, so elements above strontium in the same group have smaller radii.
What elements is the smallest Ca Mg Be Sr?
Among the elements listed—calcium (Ca), magnesium (Mg), beryllium (Be), and strontium (Sr)—beryllium (Be) is the smallest in terms of atomic size. This is because beryllium is higher up in the periodic table, with fewer electron shells compared to the other elements, resulting in a smaller atomic radius.
Can you describe the general trend in atomic radius in group 2A?
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
Which element has a smaller atomic radius bromine or gold?
The atomic radius of bromine is lower.
Which has a greater atomic radius at atom of fluorine or an atom of beryllium?
An atom of fluorine
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
Is magnesium smaller than Beryllium?
No, magnesium is not smaller than beryllium. In the periodic table, magnesium (Mg) has an atomic number of 12, while beryllium (Be) has an atomic number of 4. As you move down the periodic table, atomic size generally increases due to the addition of electron shells, making magnesium larger than beryllium.
