Answer:
5 neutrons
Explanation:
There five isotopes of lithium. The most stable and abundant is lithium-7.
Its percentage is 92.5%. It has four neutrons. All lithium isotopes have same atomic number but different atomic mass because of different number of neutrons.
Lithium-8 have five neutrons.
Lithium-9 have six neutrons.
Lithium-11 have eight neutrons.
Lithium-4 has one neutron.
Lithium is alkali metal.
It is present in 1st group.
Its atomic number is 3.
Its atomic mass is 7 amu.
Lithium salts are used in psychiatric medicine.
Answer:
<h2>Transverse wave,</h2>
Explanation:
<h3>motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.</h3>
Methane CH4 CH4 1 hexane C6H14 CH3(CH2)4CH3 5
ethane C2H6 CH3CH3 1 heptane C7H16 CH3(CH2)5CH3 9
propane C3H8 CH3CH2CH3 1 octane C8H18 CH3(CH2)6CH3 18
butane C4H10 CH3CH2CH2CH3 2 nonane C9H20 CH3(CH2)7CH3 35
pentane C5H12 CH3(CH2)3CH3 3 decane C10H22 CH3(CH2)8CH3 75
Depends on the situation. If the nucleophile is already in excess, then no the reaction will not occur faster
