1) <span>this ion is an anion
cations are ions which have given out electrons and are positively charged
anions are ions which have taken in electrons and are negatively charged. the ion given has a negative charge which means it has taken in an electron therefore its an anion.
2)</span><span>what is the chemical symbol of the noble gas this ion is isoelectronic with ? atomic number of the ion is 10, this corresponds to the noble gas Neon - Ne.
</span>chemical symbol is Ne
3) <span>what is the formula of the ion?
the ion has a negative charge of -1. this means it has taken in one electron hence the electronic configuration before taking in the electron, when the </span>atom is neutral is 1s² 2s² 2p⁵
then the atomic number is 9, element with atomic number is fluorine.
therefore element is F
formula of ion is F⁻
<u>Answer:</u> The beta-particle is being released in the reaction and the nucleus is changing from to nitrogen.
<u>Explanation:</u>
Carbon-14 undergoes a radioactive decay by the process of beta-minus decay.
In beta-minus decay, a neutron gets converted to a proton and an electron.
The equation for the beta-minus decay of carbon-14 follows the reaction:
In this reaction beta-particle is being released carrying -1 charge. Another name for this particle is known as electron.
In this decay process, the nucleus is changing from carbon to nitrogen. The property of the nucleus is changing completely as number of protons is getting increased.
Answer:
<em>The ionic radius is the the distance from the nucleus to the outermost electrons in a ion. While the atomic radius is the distance from the nucleus to the normal valence electrons.The ionic radius is half the distance between two gas atoms that are just touching each other. If the atom loses its outermost electron (positively charged or cation), the ionic radius is smaller than the atomic radius because the atom loses an electron energy shell.</em>
