Question

From the symbol

From the symbol 612X, identify the element and write down its mass
number and atomic number.​

Answer 1

Given :

$\sf_6^{12}X$

To find :

• Element
• Atomic number of element
• mass number

Solution :

Whenever an element is represented as :-

$\sf_d^{c}A$

Then A is symbol of that element. Symbol is used to represent elements in short form. Fir example symbol of Hydrogen is H , Aluminium is Al and so on. Every element has unique symbol.

Now c represents mass number of element A.

d represents atomic number of element A.

So now in the question it is given :-

$\sf_6^{12}X$

So, atomic number of given element X is 6. That means X is Carbon.

Mass number is 12 .

X = C ( carbon)

Answer :

• Element = carbon
• Mass number = 12
• Atomic number = 6
