Which of the following statements is true? Protons and electrons are found in the nucleus.
Atomic weight and atomic mass are the same.
Isotopes have different numbers of electrons.
Weight depends on the amount of gravity.

Atoms that have the same number of peg holes may have similar chemical Although a proton has more mass than an electron, they both have the same amount of stability of the nucleus, and hence the atom's radioactivity,

Explanation:

weight depends on the amount of gravity

Explanation:

an objects weight depends on it's mass and the strength of the gravitational pull.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

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.
