 Okay, so it says, name the period 3 element with the following ionization energies in right it's electron configuration, so the ionization energies are 1, 12, 1903, 2910, 49, 56, 62, 78, 22, 23, 0. So it says it's a period 3 element, that would be sodium, right, so where's the big one? And right here, right, okay, so sodium, right, magnesium, alumina, silicon, phosphorus, salt, right, and then it says write the electron configuration, let's just do it since the question says that. Let's write the electron configuration for phosphorus, what is it? 1s2, 2s2, 236, 3s2, 3p, so, and then another way, 1, 2. Questions on that before we move on to lab? Okay, good job guys.
