Na. Si is often considered a semi-metal or metalloid.
C-P 14K likely refers to the metal composition of the ring. "C-P" is likely the manufacturer's mark or logo, and "14K" indicates that the ring is made of 14 karat gold, which is a common type of gold used in jewelry.
These elements (1 to 30) are: H, He, Li, Be, B, C, N, O, F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn. The element with the atomic number 30 is zinc (Zn).
Hydrogen (H) Helium (He) Lithium (Li) Beryllium (Be) Boron (B) Carbon (C) Nitrogen (N) Oxygen (O) Fluorine (F) Neon (Ne) Sodium (Na) Magnesium (Mg) Aluminum (Al) Silicon (Si) Phosphorus (P) Sulfur (S) Chlorine (Cl) Argon (Ar) All these elements are classified as metals, except for hydrogen and helium, which are nonmetals or noble gases.
The melting point of p-phenylenediamine is around 142-143°C.
The group 5A non-metal that is a solid at room temperature is phosphorus with the symbol P.
C, H, O, N, Fe, Si, Al, Ca, S, Na, P
These elements are (in the Earth crust): Si, Al, O, Ca, Mg, Fe, Na, K, H, C, Ti, P.
These elements are (in the Earth crust): Si, Al, O, Ca, Mg, Fe, Na, K, H, C, Ti, P.
ewan. :P bahala na si batman!

H, He, Li, Be, B., C, O, N, F, Ne, Na, Ma, Al, Si, P, S, Cl, Ar, K, Ca.
Ar > Si > Mg > Na > P. Atomic radius generally decreases from left to right across a period due to increasing effective nuclear charge, but increases down a group due to additional electron shells.
8 - Na, Mg, Al, Si, P, S, Cl, Ar
Only a lot of compounds in tooth paste (mixture of many compounds), no elements.
all metal which have 3 electron in valance band mixed in the pure semiconductor (like Ge,Si) are called p-type impurities
Sodium (Na) is the most metallic among the elements listed (P, Al, Ar, Na). It is located in Group 1 of the periodic table, which is known as the alkali metals group and is known for its high metallic properties such as luster, conductivity, and malleability.
Sodium (Na) and Magnesium (Mg) are two elements in the same period (period 3).
