Answer:
x y
A and A, where x and y are the mass b b numbers, b is the atomic
and A is the chemical symbol of the element
They are different because they have different mass numbers and are similar because they have the same atomic number
Explanation:
Isotopes are atoms that have the same atomic number but different mass numbers due to the difference in neutron number.

BLUE BOX CA BE REFERRED AS AN ELECTRONIC DEVICE WHICH IS USED IN THE TELEPHONIC CIRCIUTSTI PASS ON LONG DIATANT SIGNALS.
Answer:
True
Explanation:
Molecular mass of :
Molecular mass of Ca + molevular mass of C + molecular mass of O × 3
40g + 12g + 16 × 3g
= 40g + 60 = 100g
Thus its true
