Chemistry Homework Assistance
QuestionAI's chemistry problem solver is a middle school chemistry tutoring tool that summarises key chemical reactions and equations in real-time, featuring a robust learning system to empower even those with a weak foundation in chemistry.
You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.

- What is the group (top to bottom) trend in the first ionization energies?Why? It increases because the nuclear charge increases It decreases because the distance from the nucleus to the valence electrons increases It decreases because the nuclear charge decreases It increases because the distance from the nucleus to the valence electrons decreases
- What is the period (left to right) trend in the first ionization energies? Why? It decreases because the nuclear charge decreases It decreases because the distance from the nucleus to the valence electrons decreases It increases because the nuclear charge increases It increases because the distance from the nucleus to the valence electrons increases
