92 protons 143 neutrons and and atomic mass of 235 how many electrons does atom have

92.

For all elements, the amount of electrons will always equal the amount of protons. The only time this will change is when it has a charge, for instance, 92 or Uranium, typically has no net charge. If we used the example of Oxygen however, it has a net charge of 2-, meaning that the amount of electrons would increase by 2 to bring Oxygen to stability.

For net charges, the signs mean opposing things: - means gains while + means loses.

Hope this helps!

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.
