Using the periodic table and your knowledge of atomic structure. cobalt (co) and nickel (ni) have almost identical atomic mass numbers. comparing the typical nickel and cobalt atoms, which statement best describes the atoms?
a) nickel has one more neutron.
b) cobalt has one less proton.
c) both atoms will have the same number of protons.
d) both atoms will have the same number of neutrons.

Option B is the right answer

Explanation:

As Cobalt has 27 protons & Nickle has 28 protons according to the periodic table . So Nickle has one more proton than Cobalt .

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.
