Answer:
119
Explanation:
Tin is present in group sixteen. Its atomic number is 50 and atomic weight is 119 amu.
The atomic number is the number of electrons or number of protons. The atomic mass is equal to the sum of number of protons and number neutrons.
Tin have 50 protons and 69 neutrons.The atomic weight will be 50+69 = 119 amu.
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons.
The answer is A) Electrons are exchanged.
All reactions that involve molecular oxygen, such as combustion and corrosion, are electron transfer reactions. This includes the rusting of iron.
Answer is: <span>name of the product nuclide is thorium-230.

<span>Alpha particle is
nucleus of a helium-4 atom, which is made of
two protons and two neutrons.
²³</span>⁴U → ²³⁰Th + α (alpha
particle).
Alpha
decay is radioactive decay in which an atomic
nucleus emits an alpha particle (helium nucleus) and transforms
into an atom with an atomic number that is reduced by
two and mass number that is reduced by four.
ANSWER: because they are not created or destroyed they are just rearranged to form the products
The factor that determine how water cycles on earth is the forms that water is found in[solid, liquid and gas].
