Write the condensed ground-state electron configurations of these transition metal ions, and state which are paramagnetic:
serg [7]

The ground-state electron configurations of Cd^{2+} transition metal ions are diamagnetic [Kr] 4d^{10}. The ion is diamagnetic because there all electrons are paired.

<h3>What is Diamagnetic?</h3>
  • A magnetic field repels diamagnetic materials because it induces an opposing magnetic field in them when it is applied, which produces a repelling force.
  • In contrast, a magnetic field draws paramagnetic and ferromagnetic materials together.
  • All materials experience the quantum mechanical phenomenon known as diamagnetism, which is the only source of magnetism in a material.
  • The magnetic dipoles within paramagnetic and ferromagnetic materials exert an attracting force that outweighs the modest diamagnetic force.
  • Diamagnetic materials have a magnetic permeability that is less than vacuum, or 0.
  • Although superconductors behave as strong diamagnets, diamagnetism is often a modest effect that can only be observed by sophisticated laboratory equipment.

Hi:)) how to do 5? I’m not sure if it’s hydrogen carbonate or carbonate
zysi [14]

Answer:

copper(ll) carbonate

Explanation:

Since the product is a salt which is copper(II) carbonate, water and carbon dioxide, this reaction is an acid + metal carbonate reaction.

Looking at the salt, Cu²⁺ has to be part of the reactants.

Hence, the missing compound there has to be copper(ll) carbonate, CuCO₃.

The balanced chemical equation would be:

CuCO₃ + 2HNO₃➙ Cu(NO₃)₂ +H₂O +CO₂

P.s. You left out CO₂ as a product in Q2 ;)

Just a recap of the main reactions you would've learnt:

1) Acid + base/ alkali ➙ salt + water

2) Acid + metal ➙ salt + hydrogen gas

3) Acid + metal carbonate ➙ salt + H₂O + CO₂

In a ground state hydrogen atom in which orbital is the electron
vagabundo [1.1K]
The function is known as the atomic orbital. 
The electron is most likely to be found at a distance from the nucleus equal to the Bohr radius.

For Hydrogen,...

an electron in the ground state has the energy of -13.6eV.
This is relative to the ionization threshold. 

Hoped this helped ;)<span />
