The correct answer in this question is option B. The electronegativity increases across a group. Chlorine ion has a higher electronegativity than the sodium ion. Chlorine need one electron to have a noble gas configuration that is why it gets one electron every chance it makes.

true or false, Valence bond theory states that a bond between two atoms is the strongest when the nuclei of the atoms are touchi
pentagon [3]

Valence bond theory stating that a bond between two atoms is the strongest when the nuclei of the atoms are touching each other is true.

<h3>What is Valence bond theory?</h3>

This theory states that when two valence orbitals of two different atoms overlap on each other, the bond is usually strong.

The bond formed in this scenario is usually covalent which involves sharing of the valence electrons.

Which type of nuclear decay is the radioactive isotope fe2659 likely to undergo?
jekas [21]

Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

Whenever there are too many protons or even neutrons in a nucleus, one of the protons and neutrons will turn into the other, which is known as beta decay. During beta minus decay, a neutron transforms into a proton, electron, as well as antineutrino.

Fe_{26} ^{59} → Co_{27} ^{59} +\beta_{1}  ^{0}

It can be seen that after the beta minus decay Fe changes into Co.

In beta decay , decrease in atomic number by one unit Fe atom get converted into Co atom.

Neutron-rich nuclei often decay by producing both an electron and an antineutrino.

Therefore, Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.
