Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
Answer:
Determining what data to collect.
Explanation:
You can use the periodic table to help you determine the charge of an element when it becomes an ion. You base this on the group 8 elements called the noble gases. You can determine the charge by finding the difference of the atomic numbers of the given element to their nearest noble gas. It is made easier for elements on the left side. You can take their charge to be their group number. Since calcium is in group 2A, it will have a charge of 2+. Since Na is in group 1A, it will have a charge of 1+. Since Phosphorus is a nonmetal, it will have a negative charge because it needs to gain electrons to achieve their nearest noble gas. Since the nearest noble gas is Argon having an atomic number of 18, while Phosphorus has an atomic number of 15:
Charge = 15 - 18 = -3
The charge of Phosphorus is -3.
