There are many different examples one might reference when it comes to elements of art. For example, the two elements of art for a sculptor would be space and form.
M2+ ions are common for transition elements because they involve the loss of two electrons from the outermost d orbital, leading to a stable configuration. Transition metals have partially filled d orbitals and can easily lose two electrons to achieve stability in the +2 oxidation state. This makes M2+ ions a common oxidation state for transition elements.
Cr and Fe have four unpaired electrons in their 2 plus ions.
He was able to work out the atomic mass of the missing elements, and so predict their properties. And when they were discovered, Mendeleev turned out to be right. For example, he predicted the properties of an undiscovered element that should fit below aluminium in his table. When this element, called gallium, was discovered in 1875, its properties were found to be close to Mendeleev's predictions. Two other predicted elements were later discovered, lending further credit to Mendeleev's table.
Most are represented by two letters. It would be impossible for most to be represented by one letter as there are more than twice as many elements as there are letters.
It is impossible to predict the reactivity of undiscovered elements without knowing their properties and behavior. Reactivity is influenced by an element's electron configuration, atomic structure, and other factors that require detailed analysis. Therefore, it is uncertain if elements A plus 1 and D plus 2 would react without more information.
The two main factors that led to the widespread acceptance of Mendeleev's periodic table were its accurate prediction of the properties of then-unknown elements and its ability to explain the periodic trends observed in elements. Additionally, Mendeleev's table was able to organize the known elements in a logical and systematic manner, making it easier to understand and use.

Not necessarily. The overall charge on a compound formed by the joining of two elements depends on the specific elements and their oxidation states. It could be positive, negative, neutral, or even fractional, depending on the elements involved in the chemical reaction.

If the unknown substance contained a mixture of two elements, it would exhibit properties that are a combination of those two elements. Its physical and chemical properties would be unique to the mixture, and further analysis would be needed to identify the specific elements present in the substance.
