In the third period of the periodic table sodium is followed by magnesium aluminum silicon and phosphorus which has the smallest atomic size?
In the third period of the Periodic Table, phosphorus has the smallest atomic size. Atomic size generally decreases across a period from left to right due to increasing nuclear charge, which pulls electrons closer to the nucleus. As sodium is on the far left and phosphorus is further to the right, phosphorus exhibits a smaller atomic radius compared to sodium, magnesium, and aluminum.

What are the two elements in the same period as magnesium?
Magnesium is in period 3 of the periodic table. The two elements in the same period as magnesium are aluminum (Al) and silicon (Si). Both elements follow magnesium in this period, with aluminum located to the right of magnesium and silicon further to the right.
What are the first 20 elements of the pedriotic table?
The first 20 elements of the periodic table are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, and calcium.
What are the following elements that are in the same period as magnesium?
Magnesium is in Period 3 of the periodic table. The elements in the same period as magnesium (atomic number 12) include sodium (11), aluminum (13), silicon (14), phosphorus (15), sulfur (16), chlorine (17), and argon (18). These elements share the same highest energy level, which is the third shell in this case.
How many elements present in third periodic table?
Now (January 2012) the periodic table of Mendeleev contain 118 chemical elements.
Which has the larger firs ionization energy magnesium or phosphorus why?
Phosphorus has a larger first ionization energy than magnesium. This is because ionization energy generally increases across a period in the periodic table due to increasing nuclear charge, which holds electrons more tightly. Magnesium is in Group 2, while phosphorus is in Group 15, leading to phosphorus having more protons and a stronger attraction for its valence electrons, resulting in higher ionization energy.
Which element is in the same period as phosphorus - carbon nitrogen oxygen and magnesium?
The only element out of those listed which is on the same row of the periodic table as phosphorus is magnesium.
Which element is in the same period as sodium?

Which is the least reactive sodium aluminum or magnesium?
Aluminum is the least reactive among sodium, aluminum, and magnesium. This is because aluminum is more stable due to the presence of a protective oxide layer on its surface, which prevents further reactions. Magnesium is more reactive than both sodium and aluminum.
