________ is defined as the number of protons plus the number of neutrons. ________ is defined as the number of protons plus the
velikii [3]

Answer:

Mass number is defined as the number of protons plus the number of neutrons.

Explanation:

Every atom of an element have proton(s), neutron(s) and electron(s). The proton number of an element is the atomic number of that element. For an electronically neutral atom the proton number is equal to the electron numbers. The neutron and the proton contributes to the mass of every atom. The electron is more active when atoms are bonding.

Mass number of an element is the number of proton plus the number of neutron.  

Atomic number of an atom is the number of proton present, so it can never be atomic number.

Isotopy talks about same element having different number of neutron but same number of protons in each atom.  Example is hydrogen that exist as protium, deuterium and tritium. It cannot be isotopic number.

Ionic number talks about elements that possess a charge. The elements have been ionized.

The answer is Mass number because the sum of proton number and neutron number is equals to mass number.

How much mass is lost through radioactive decay if 1.8 x 1015 Jare.
ser-zykov [4K]

The mass lost through radioactive decay is 0.094 kg.

<h3>What is the mass lost in a radioactive decay?</h3>

The mass loss in a nuclear reaction such as a radioactive decay is known as mass defect.

The lost mass is converted to energy released during the decay process.

The energy and mass are related by the formula:

  • E = mc²

where

m is mass

E is energy

c is speed of light = 3.0 * 10⁸ m/s

Mass lost = E/c²

mass lost = 8.5 * 10¹⁵/(3.0 * 10⁸)²

mass lost = 0.094 kg

Therefore the mass lost is 0.094 kg.
