for the compound Pbl2 what is the charge on lead

1.)

Given the following (fictional) ions: cations anions D+1 M1 E+2 (LB4) 2 (ZG2)*3 (ZEm) 2 At3 R 3 Write the balanced chemical formula for the ionic compound that would form between the following pairs of ions. a) ZG2 and D*1 b) A and LB4

Can someone please show me how to figure these out? Thank you!

Give the charge on the atom indicated and give the overall charge on the molecule/ion.

QUESTION 1 Fill in the missing information: formulas for missing compounds and ions, systematic/modern names of compounds, and whether the compound is ionic (I), covalent (C) or both (B). { NOTE: i) Write subscript numbers in the formulas as if you are writing letters in a word (e.g., Mg3N2 should be written as Mg3N2). ii) Do not put parentheses around monatomic ions but put them around a polyatomic ion if there is more than one in the formula (e.g. Na2C03 should be written as Na2CO3 but Ca(NO3)2 as Ca(NO3)2. )} (Use the letters I, C, or B to indicate the type of bonding in the compound.) Compound Formula Name of compound lonic (I), Covalent (C) or Both (B)? lons 2- 1+ NH 4 & SO 4 4+ Sn & CI 1- 2+ Fe & CH 3 CO0 1- AI 3+ & p 3- AIP
