Want this question answered?
Sodium has a larger atomic radius and is more metallic.
yes
Sodium has a larger atomic radius than aluminum.
The potassium atom has a larger radius. When potassium loses an electron to become a cation (positively charged ion), it also loses the energy level in which the electron was. Therefore the potassium ion is smaller that the potassium atom.
No. Lithium and sodium are both from the same column of the periodic table and so have similar chemical properties. Lithium is atomic number 3 with a weight of 6.94. Sodium is much bigger and heavier with an atomic number of 11 and a weight of 22.99.
Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.

No. A cesium atom is larger both in terms of atomic mass and atomic radius.
The potassium atom has a larger radius. When potassium loses an electron to become a cation (positively charged ion), it also loses the energy level in which the electron was. Therefore the potassium ion is smaller that the potassium atom.

For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
a larger nuclear charge
Sodium - Na Potassium - K
Sodium and potassium are two different albeit similar elements. A neutral sodium atom has 11 protons, 11 electrons and typically 12 neutrons. It forms and ion with 10 electrons. It has an atomic radius of 186 picometers. Potassium has a large, heavier atom than sodium A neutral potassium atom has 19 protons, 19 electrons ans usually 20 neutrons. It forms an ion with 18 electrons. Potassium's atomic radius is 227 picometers. Additionally, potassium is somewhat more reactive than sodium and has a lower melting point.
Potassium is a non metal element. Atomic number of it is 39.
