Selenium (Se) the most common isotope of this element. The nucleus consists of 34 protons (red) and 46 neutrons (blue).
Answer:
B) a neutron
Explanation:
The mass of a proton is approximately the mass of a neutron.
Both a neutron and proton are nuclear particles that are found within the nucleus of an atom.
Protons are the positively charged particles within an atom.
Neutrons do not have any charges on them.
Approximately the mass of:
Protons = 1.67 x 10⁻²⁷kg
Neutrons = 1.68 x 10⁻²⁷kg
it is much more efficient and environmentally conscious.
Sodium Chloride is a example of a ionic bond one atom is positively charged while the other is negatively charged both end up becoming neutral charge after they bond. check my answer to make sure that statement is accurate.
3/2(x-5)=-6
3x-15=-6*2
3x=-12+15
3x=3
x=3/3
x=1
