Using complete subshell notation (1s2 2s2 2p6, and so forth), predict the electron configurations of the following ions. Calcium cation (Ca+2)

Write the complete electron configuration of copper. Write the noble gas configuration of the copper (II) ion, Cu²*. Write the complete electron configuration for the tin. Write the complete electron configuration for the tin (IV) ion, Sn4* Write the noble gas configuration of the tin (II) ion, Sn²+ Draw the energy level diagram for nickel. Use appropriate labels to identify components of the diagram. A common ionic charge (or valence) of nickel is 2+. Write the electron configuration for the nickel(II) ion.

Out of these sentances , choose the one that is correct (there may be multiple correct statements) 1. Sodium has a bigger first ionization energy than potassium  2. sodium has a bigger atomic size than clorine 3.calcium has a bigger fist ionization energy than fluorine does 4. sulfur has a bigger electronegativity than chlorine

Please provide the chemical symbol for the element with the following electron configuration.                                 1s2 2s2 2p6 3s1

Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. ionization energy ionization energy required required Cs - Cs + e Se » Se - e Не — Не +e ? Ci Cl' + e Rb - Rb + e v ? Те — Те +e ? 1 (least) 3 (most)

The graph below represents successive ionization energies (IEs) in kJ/mol for a particular element in period 3. Identify the element. 35000 30000 ll 25000 20000 15000 10000 5000 IE1 IE2 IE3 IE4 IES IE6 E7 E8 O Chlorine O Aluminum O Phosphorous Silicon O Argon Oxygen

These two problems are connected and I don't know how to do these.

Give the electron configurations for the following atoms. Do not use the noble gas notation. Write out the complete electron configuration. Example: Mg 1s2s²2p°3s² Element Electron configuration N Sc Li Cu

Since the first ionization energy of rubidium is +403 kJ mol, how many kJ of energy is it required to convert 22.90 g gaseous rubidium to +1 monoatomic ion at constant temperature?

Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. ionization + Pb → Pb + e He + ► F + e F→>> + - → He + e ? ? energy required ?
