All are metals.
C and N, N and H, Cl and Cl, Xe and Xe can form covalent bonds. Mg and Cl, Li and Cl, Cu and Cl, Fe and Cl can form ionic bonds due to the large difference in electronegativity. K and Cl would form an ionic bond as well.
The chemical symbols of gold, copper, potassium, silver, platinum, and Iron are Au, Cu, K, Ag, Pt, and Fe respectively.
K. Cu. Cl
fecl3 is a compound called iron chloride. i2 is an element called iodine. fes is a compound called iron sulphide. s and k are elements sulpher and potassium
The most reactive series is the reactivity series of metals, which ranks metals from most reactive to least reactive based on their tendency to undergo chemical reactions. The series is a useful tool in predicting how metals will react with other substances.
(Na, K, Ca, Mg, P, Fe, Cu, Zn, Mn and B
N, P, K, Fe, Mg, Zn, S, Cu etc.
Copper (Cu) is the most metallic element among potassium (K), krypton (Kr), iron (Fe), and copper (Cu). It exhibits high metallic properties such as conductivity and luster.
C and N, N and H, Cl and Cl, Xe and Xe can form covalent bonds. Mg and Cl, Li and Cl, Cu and Cl, Fe and Cl can form ionic bonds due to the large difference in electronegativity. K and Cl would form an ionic bond as well.
These symbols are the standardized symbols for chemical elements: some examples are Na, K, Li, Ca, Mg, Th, Cu, Fe etc.
Macronutrients are proteins, fats, carbohydrates; micronutrients are Na, Ca, P, K, Fe, Cu, Ni, Se, Mg, N, etc.
