Three different atoms or atomic cations with 28 electrons

answer:

the chemical symbols for three different atoms or atomic cations with 27 electrons are

explanation:

an atom is neutral specie with equal number of electrons and protons in it.

atomic number =   number of protons = number of electrons

atomic number =- number electrons = 27

the atom with 27 atomic number cobalt that co.a cation is an ionic species which carry positive charge.when an atom looses an electron it forms cation.

copper has atomic number of 29. when the copper atom looses 2 electrons it get converted into copper cation that is   with 27 electrons in its ion.

nickel has atomic number of 28.when the nickel atom looses 1 electron it get converted into nickel cation that is   with 27 electrons in its ion.so,the chemical symbols for three different atoms or atomic cations with 27 electrons are

did this question in high school lol

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
