Which of the following describes a particle that contains 36 electrons, 49 neutrons, and 38 protons?
A. an ion with a charge of 2 -
B. an ion with a charge of 2 +
C. an atom with a mass of 38 amu
D. an atom with a mass of 49 amu

Sagot :

Indrawboyidn

The positively charged element (cation) with a charge of +2(B)

Further explanation  

The Atomic Number (Z) indicates the number of protons in an atom of an element. If the atom is neutral then the number of protons will be equal to the number of electrons. So the atomic number can also indicate the number of electrons.  

So atomic number = number of protons = number of electrons  

Mass Number (A) is the sum of protons and neutrons  

Mass Number (A) = Number of protons + Number of Neutrons  

So that the relationship between atomic numbers and mass numbers can be formulated as follows:  

Atomic Number (Z) = Mass Number (A) - Number of Neutrons  

A particle that contains 36 electrons, 49 neutrons, and 38 protons

atomic number = number of protons = number of electrons  

The atomic number is based on the number of protons because the element tends to release or bind electrons to achieve the stability of the electron configuration

so the atomic number = proton number = 38

Mass Number (A) = 38 + 49 = 87

Number of protons = number of electrons found in the neutral element

if the number of protons is not the same as the number of electrons, then the element is called charged

  • number of protons> number of electrons = positively charged element
  • number of protons <number of electrons = negatively charged element

because in the problem, the number of protons> the number of electrons, then the positively charged element is:

number of protons - number of electrons = 38 - 36 = +2
