26, protons and nuetrons will always be the same
The atom will lose three valence electrons.
<h3>What is meant by valence electron ?</h3>
- A valence electron is an electron that is part of an atom's outer shell in chemistry and physics. If the outer shell is open, the valence electron can take part in the creation of a chemical bond.
- Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
- The chemical properties of an element, such as its valence—whether it can bond with other elements and, if so, how readily and with how many—can be affected by the presence of valence electrons. In this way, the electronic configuration of an element greatly influences its reactivity.
- A valence electron for a main-group element can only be found in the outermost electron shell; for a transition metal, it can also be found in an inner shell.

Answer:
Constraints are restrictions that need to be placed upon variables
Explanation:
Constraints are restrictions (limitations, boundaries) that need to be placed upon variables used in equations that model real-world situations. It is possible that certain solutions which make an equation true mathematically, may not make any sense in the context of a real-world word problem.
