Answer:
Iron (Fe)
Explanation:
The number of electrons (-) is usually the same as the number of protons (+) in the atom of the element (unless it is an ion).
The element described has 26 electrons, so we can assume that it has 26 protons as well. The number of protons in an atom is the atomic number of element that the atom is.
Element 26 on the PTE is Iron (Fe), which does rust (oxidation) in air and water.
Answer:
solubility
Explanation:
solubility is a measure of how much a substance will dissolve in a solvent.
Zero on a pH scale is very A. acidic, and 14 on a pH scale is very basic.
The lower the number on the scale, the more acidic it is.
Answer:
A +1 Ion of Lithium
Explanation:
Lithium has the atomic number of 3, therefore it has 3 protons
An electron has a negative charge, so losing an electron gives an atom a positive charge.
Xenon. It is located in the last group of the periodic table.
