Answer:
D.4
Explanation:
Number of neutron= mass number - atomic number
where; d no of neutron is 5
d mass no is 9
atomic number be x
5=9-x
x=9-5
x=4
This is a biology question not a chemistry question. But these are all types of cells related to different cell division techniques. does that help?
<span>C-C and C-H bonds are relatively stable because
they have low bond dissociation energy
13. Dispersion forces are caused by the __________,
motion of electrons
Hope this answers the question. Have a nice day.</span>
One valence electron is lost by Lithium
<h3>What is Electron ?</h3>
Unattached or attached to an atom, an electron is a negatively charged subatomic particle. One of the three main types of particles within an atom is an electron that is bound to it. The other two are protons and neutrons.
- Due to the fact that full valence shells are more stable states and that all noble gases have them, lithium wants to lose electrons in order to become like helium. Consequently, alkali metals lose one electron to achieve the closest noble gas configuration.
- Each lithium atom loses an electron to become a Li+ cation when it forms chemical compounds with other elements. The anions in ionic compounds that are negatively charged are therefore attracted to these. There are many applications for lithium compounds.
- Since full valence shells are more stable states, and all noble gases have them, lithium wants to lose electrons to become like helium. In order to obtain the nearest noble gas configuration, alkali metals must lose one electron.
