I know how to do electron configuration, but I think I’m doing the rest wrong. Answers and explanations would be much appreciate
Natasha_Volkova [10]

Your answers seem great so far, except for a tiny issue: With the ionic symbols, try to get into the habit of using "+", with metals, like sodium, and try to use the integer first. So, for example, a potassium ion would be K^+, while an oxide ion would be O^2-


Let's take aluminium as an example I'll work through:

Aluminium, with it's atomic number of 13, will have an electronic configuration of 1s2 2s2 2p6 1s2 2p1. So it would have 2, 8, 3 electrons in the first three energy levels, respectively.

Usually, if an elemental atom has a valence electron (highest energy level electron) count less than 4, it almost always will lose electrons. Since aluminium has 3, it will also lose the electrons.

It loses the 3 valence electrons, and so will end up with 10 electrons.

Since the atomic number also tells how many protons it has, we know that an aluminium atom has 13 protons, which doesn't change.

Since the size of the charges of a proton and an electron are the same, with protons being positive and the electrons being negative, an aluminium ion would have a charge of +3, and the Ionic symbol would be Al^3+



Hope I helped! xx

In the cathode ray tube experiment, J. J. Thomson passed an electric current through different gases inside a cathode ray tube i
Ber [7]

It showed that atoms can be divided into smaller parts.

It showed that all atoms contain electrons.

Explanation:

The experiment carried out by J.J Thomson on the gas discharge tube by passing electric current through a tube filled with many different gases provided a good insight into the structure of an atom.

This experiment led to the development of the plum pudding model of the atom.

  • Cathode rays and it properties were discovered in this set up.
  • It furnished the scientific community with evidences that atoms can be divided into smaller parts.
  • Since atoms now contain some subatomic particles, they can be broken down in like manner into further bits.
  • The cathode rays which were later termed electrons became a fundamental particles known for every atom.
