No, the number of electrons increases as you move to the right.
28 Right there on your periodic table.
The elements on the right side of the periodic table with electrons sequentially filling orbitals in their valence are known as the "p-block elements". These elements include groups 13 to 18 on the periodic table.
From left to right and into the upper corner of the periodic table electronegativity increases. Fluorine is the most electronegative element, but the elements in group 18 generally have no electronegativity at all.
Electronegativity generally decreases as you go down a group on the periodic table due to the increasing distance between the nucleus and valence electrons, reducing the attractive force. Across a period, electronegativity generally increases due to the increasing nuclear charge, pulling valence electrons closer and increasing their attraction.
Calcium has 20 electrons
This is not accurate. The number of electrons in an atom does not decrease as you move from left to right in the periodic table. The number of electrons increases across a period, as you move from left to right, based on the atomic number.
An anion is a negatively charged ion that forms when an atom gains electrons. Anions are typically found on the right side of the periodic table among nonmetals.
Increasing (valance) electrons.
False
The number of electrons in the atom increase from left to right and then from top to bottom.
Givers are elements on the left side of the periodic table, known as metals, which readily give away electrons to form positive ions. Takers are elements on the right side of the periodic table, known as nonmetals, which tend to accept electrons to form negative ions.
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
