Ionization energy generally increases across a period from left to right due to increasing nuclear charge, which holds electrons more tightly. Conversely, ionization energy decreases down a group as additional electron shells are added, increasing the distance between the nucleus and the outermost electrons, making them easier to remove. Therefore, elements located further to the right in a period and higher up in a group tend to have higher ionization energies compared to those further left or lower down.

Are two types of atoms metallic and nonmetallic?
Metallic and non-metallic is one of many ways of categorizing chemical elements. Metallic elements have a structure that allows free electrons to migrate from atom to atom within the structure of the material. These are called "conductors". Nonmetallic elements generally prevent the movement of electrons from atom to atom; they are "insulators". Starting after World War II, Dr. Robert Shockley developed another class of materials that sometimes would, and sometimes would not, conduct electricity. He called these "semi-conductors", and his discoveries form the basics of modern electronics.
Why did Dimitri Mendeleev predict that more elements with specific properties would be discovered?
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his periodic table. so he concluded that more elements with specific properties would be discovered.
Do you predict would exhibit similar properties following these three elements Carbon Nitrogen and Phosphorous?
dabbing on them haters which I mean is A answer choice A
How Which element require the greatest amount of energy to remove an electron?
Core electrons. Probably the 1s level would require the most ionization energy to pull these electrons.
Would you expect metals or nonmetals in the same periods to have higher ionization energies?
Non-metals have higher ionization energies within the same period. This is because non-metals want to gain electrons to be able to be like the nearest noble gas.
A diatomic element with a high ionization energy would most likely be?
A diatomic element with a high ionization energy is likely to be an element that forms strong covalent bonds between its atoms. Examples of diatomic elements with high ionization energies include nitrogen (N2) and oxygen (O2) due to the strong triple and double bonds, respectively, they form between their atoms.

Based on the periodic table which element would be expected to have the lowest ionization energy?
Francium would be expected to have the lowest ionization energy, as it is located in the alkali metal group at the bottom left of the periodic table. Alkali metals typically have the lowest ionization energies due to their large atomic size and low effective nuclear charge.
Could you predict that bromine would be a poor conductor of electricity based on the fact that it is a nonmetal in the halogen family?
Yes, bromine would be a poor conductor of electricity. Nonmetals, especially those in the halogen family, tend to be poor conductors of electricity because they have high ionization energies and do not readily lose electrons to form ions for conducting electricity.
Why does ionization take energy?
The first electrons to be removed (1st ionization energy) are the ones that are farthest from the nucleus, and so are not held as tightly (further from the positive protons). As you move closer to the nucleus (2nd and 3rd ionization energies), it becomes harder (more energy) to remove them because they are held more tightly by the protons.
What enable Mendeleev to predict that certain elements would eventally be discovered?
U should know this.
How are the topics of ion formation and periodic trends related?
Periodic trends affect how certain elements on the periodic table react with each other. For example, Ionization energy tend : metals want to give off electrons , non metals want to gain electrons. This trend is essentially which elements are likely to react together and how they would react together, which is essentially ion formation (gain or loss of electrons through a reaction).

What are the element within any giving periodic table would always have the lowest first ionization energy?
Elements in the alkali metal group (Group 1) have the lowest first ionization energy within any periodic table. This is because they have a single electron in their outermost shell, which is easier to remove compared to other elements. Sodium and potassium are examples of alkali metals.
