Elements in the same group have similar characteristics because they have the same number of valence electrons, which determines their chemical properties. In contrast, elements in the same period have different characteristics because they have different numbers of energy levels and electron configurations.
The element in period 4 that would have chemical properties similar to magnesium is calcium. Both magnesium and calcium are alkaline earth metals found in group 2 of the periodic table, which means they share similar characteristics such as reactivity and the formation of basic oxides and hydroxides. Additionally, they both have two valence electrons, contributing to their similar chemical behavior.
The Periodic table is a representation of all elements grouped in a manner that lists elements with similar properties in columns. Adjacent columns have deceasing or increasing characteristics
Elements in the same period share the same number of electron shells. This means they have similar atomic sizes and properties because they have the same number of electron shells determining their size and behavior.

The late civilization of Egypt is the time period from 664 B. C to 323 B. C. The power was moving from one centralized power to multiple local powers.
various artworks were discovered with the age of changing technology.for example photography,computer designing, web messing etc.
I don't think the Mayans ever used them. I think that they used another language very similar to hieroglyphics.
The metal you are referring to is likely calcium. It is in the same period as bromine (period 4) and exhibits similar properties to magnesium due to their shared group (group 2) characteristics, such as reactivity and metallic nature.
The Han period was considered a golden age of Chinese civilization because the Chinese civilization grew during this period, advances in many parts of education was made. - Milo Matthews [muca] :]

The defining characteristics of the Maya are militarism (glorification of the military), human sacrifice, and the modern calendar

In order for historians to consider a particular time in a civilization a classical period, the civilization has to make remarkable achievements in areas such as science and art. An example is Classical Greece.
