 //Arrays can hold different data types, even other arrays! A multi-dimensional array is one with entries that are themselves arrays.
 
 //1) Define and initialize the arrays specified in the exercise to hold the name, chemical symbol and mass for different elements.
-
+let element1 = ['hydrogen', 'H', 1.008]
+let element2 = ['helium', 'He', 4.003]
+let element26 = ['iron', 'Fe', 55.85]
 //2) Define the array 'table', and use 'push' to add each of the element arrays to it. Print 'table' to see its structure.
-
+let table=[]
+table.push(element1);
+table.push(element2);
+table.push(element26);
+console.log(table);
 //3) Use bracket notation to examine the difference between printing 'table' with one index vs. two indices (table[][]).
-
+console.log(table[1]);
+console.log(table[0,1]);
 //4) Using bracket notation and the table array, print the mass of element1, the name for element 2 and the symbol for element26.
 
 //5) 'table' is an example of a 2-dimensional array. The first “level” contains the element arrays, and the second level holds the name/symbol/mass values. Experiment! Create a 3-dimensional array and print out one entry from each level in the array.
