The sum of IE1through IE₄ for Group 4A(14) elements shows a decrease from C to Si, a slight increase from Si to Ge, adecrease from Ge to Sn, and an increase from Sn to Pb. (a) What is the expected trend for IEs down a group? (b) Suggest a reason for the deviations in Group 4A(14).(c) Which group might show even greater deviations?

Tha ll ium, a neurotoxin, is the heaviest member of Group 13 of the periodic table and is found most usually in the +1 oxidation state. Aluminium, which causes anaemia and dementia, is also a member of the group but its chemicalproperties are dominated by the +3 oxidation state. Examine this issue by plotting the first. second, and th ird ion ization energies for the Group 13 elements against atomic number (you might need to refer to on line resources). Explain the trends you observe.
A fundamental relationship of electrostatics states that the en-ergy required to separate opposite charges of magnitudes Q1and Q2 that are the distance dapart is proportional to Q1XQ2/d .Use this relationship and any other factors to explain the fol-lowing observations: (a) the IE₂ of He (Z=2) is morethantwice the IE₁ of H (Z=1); (b) the IE₁ of He is less than twice the IE₁ of H.
you are designing a rocket engine th uses a mixture of hydrazine and water as a propellant. this engine will be mounted to an unmanned drone bound for hydrazine for the return launch. how much will this hydrazine weigh on the surface on venus express this quanitity in Newtons. the molecular formula of hydrazine is N2H4, you may assume the molecular weights of nitrogen and hydrogen are 14 and 1 g/mol, respectivly. Gravitational acceleration on Venus is 8.87m/s^2.
To estimate the boiling point of Oganesson by extrapolating the data for theboiling points of the other noble gases. The boiling points of the noble gases are given below: Helium -269oCNeon -246oCArgon -186oCKrypton -153oCXenon -108oCRadon -62oC 1. Make a nicely labeled graph of boiling point vs. number of electrons.Using this graph, extrapolate your data to make a prediction for the boiling point of oganesson.2. A brief explanation of why this method can be used to make a reasonableestimate of the boiling point of oganesson Your explanation should include a description of the intermolecular forces that are present in samples of these elements, and how they affect their boiling points.
