An element Y has 13 protons . with reference on Y answer these questions • •state the no of electrons and neutrons.
•what is the mass no
•how many valence electrons are there in y
•is it a metal\ non metal or noble gas
•what is its valency
•

Explanation:

Y has 13 protons and we know that Aluminium (Al) too has 13 protons.

So , element Y = Aluminium

• In an element , no. of protons = no. of electrons. So , Y has 13 electrons.

• Mass no. of Y (Aluminium) = 27.

• Also we know that ,

Mass number = no. of protons + no. of neutrons

So,

No. of neutrons = 27 - 13 = 14

• Valence electrons are the electrons which are present in the outermost shell of an element.

Electronic Configuration of Y = 2,8,3

So, Y has 3 valence electrons.

• We know that Y is Aluminium & Aluminium is a metal. So , Y is a metal.

• Valency of Y = +3

i think a, hope it .

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
