Periodic Trend:
The Atomic radius of atoms generally decreases from left to right across a period
Group Trend:
The atomic radius of atoms generally increases from top to bottom within a group. As atomic number increases down a group, there is a increase in the positive nuclear charge, however the co-occurring increase in the number of orbitals wins out, increasing the atomic radius down a group in the periodic table
Answer :
The Atom with the greatest atomic radius is chlorine. Fluorine can be ruled out because it is in the same period as oxygen and further to the right down the period. Chlorine has the largest atomic size because it is farthest down the group of any of the above elements listed.
Your answer would be "Chemical Change"
Sodium belongs to Group 1A. It means that sodium has 1 valence electron. It needs to complete its octet electron or have the same configuration of a noble gas to become a stable ion. It would likely to release 1 electron to complete its octet than accept 7 more. Therefore, its ion form would be Na+.
<h3>What's Electronic configuration?</h3>
- The arrangement of an snippet's or patch's( or other physical structure's) electrons in their infinitesimal or molecular orbitals is known as the electron configuration in infinitesimal drugs and amount chemistry.
- For case, the neon grain's electron configuration is 1s2 2s2 2p6, which means that 1, 2 and 6 electrons, singly, are present in each of the 1s, 2s, and 2psubshells.
- According to electronic configurations, each electron moves collectively within an orbital while being girdled by an average field produced by all other orbitals.
- Slater determinants or configuration state functions are used to mathematically describe configurations.
<h3>What part does electronic configuration play?</h3>
- The chemical responses that an snippet can engage in as well as the types of motes that tittles can combine into to produce more complex composites depend on the electrical configuration of the snippet.
