What elements are alien metalloids?
The metalloids are Ernst (E), highho (Hi), terriblum (T) and sississ (Ss).
Are there elements that are not on the periodic table?
Although there are elements we have not yet created or found in nature, scientists already know what they will be and can predict their properties. For example, element 125 has not been observed, but when it is, it will appear in a new row of the periodic table as a transition metal.
What element is not in a group?
Hydrogen is a very special element of the periodic table and doesn’t belong to any family.
Which alien element has an atomic number of 13?
Aluminum
Aluminum has an atomic number of 13.
What is Group 18 in the periodic table called?
noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Is Na a main group element?
Abstract. The main group elements are classified as belonging to the s- and p-blocks in the periodic table. They range from gases such as fluorine and oxygen through nonmetals (e.g., boron, phosphorus, and sulfur) and semimetals (metalloids; e.g., germanium) to very reactive metals such as sodium and potassium.
Which is not correct grouping of elements?
Answer: Compounds and alloys are not elements. Similarly, groups of electrons and neutrons are not elements.
Is Element 115 found on Earth?
Element 115 is one of a number of superheavy elements—elements with an atomic number greater than 104—that are so short-lived, they can’t be detected in nature. Scientists can, however, synthesize these elements in a laboratory by smashing atoms together.
