(a)
Interpretation: The formula (including the charge) for the simple ion that the element is most likely to form with
Concept introduction: Charge tells the number of electrons. For a neutral atom, charge is zero but if an electron is removed, atom becomes positive charge and if an electron is added, atom becomes negative charge.
(a)
Answer to Problem 39A
Explanation of Solution
To find the ionic charge of an element it is important to look at the element and identify whether the element is a transitional element or not. Because
Therefore, it is important to look at the periodic table and identify the element.
Since, Krypton has the atomic number 36 and it is an noble gas therefore the formula for Krypton along with the charge is
(b)
Interpretation: The formula (including the charge) for the simple ion that the element of atomic number 31 is most likely to form, is to be written.
Concept introduction: Charge tells the number of electrons. For a neutral atom, charge is zero but if an electron is removed, atom becomes positive charge and if an electron is added, atom becomes negative charge.
(b)
Answer to Problem 39A
Explanation of Solution
To find the ionic charge of an element it is important to look at the element and identify whether the element is a transitional element or not. Because transition element tends to have different ionic charges.
Therefore, it is important to look at the periodic table and identify the element.
Since, Gallium is in group 13 and it has an charge of
