Two particles (X) and(Y) have the comostion as shown in the table :
`{:("particle","numberof electons","number of neutrous ","Number of protons"),((X),18,16,16),((Y),18,18,17):}`
the paricle (x) and(Y) are:

Name the particle which has 18 electrons , 18 neutrons and 17 protons in it.

The number of protons, neutrons and electrons in particles A to E are given below : {:("Particle","Protons","Neutrons","Electrons"),("A",17,18,17),("B",3,4,2),("C",18,22,18),("D",17,20,17),("E",9,10,10):} Giving reasons, find a pair of isotopes from the above particles.

A particle X has 17 protons, 18 neutrons an d 18 electrons. This particle is most likely to be :

If the mode of 15, 12, 18, 8, 9, 16, 12, x, 18, 10 is 18, then the value of x is

Number of positive integer solutions (x,y,z) of xyz=18 is

The sum of two numbers is 18 and their difference is 16. Find the two numbers.
