Natalka [10]

Answer:

⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga

Explanation:

Nuclear reactions are reactions which occur with changes in the nucleus of an atom. Nuclear reactions usually occur with the release of large amounts of energy and radiation. Radiactive elements are elements that are involved in nuclearbreactions due to the unstable nature of their nucleus. They disintegrate spontaneously with the emission of radiations. The major types of radiations released during nuclear reactions are;

1, Alpha particles - these are positively charged radiations with strong ionizing power. Each alpha particle is a helium nucleus

2. Beta particles - these are very fast moving stream of electrons. They are negatively charged particles .

3. Gamma radiation - is a form of electromagnetic radiation.

In the alpha absorption of Cu-61, the proton number of the atom increases by 2 while the mass number increases by 4 and the Cu-61 atom is changed to Ga-65 atom. The nuclear equation is given as follows:

⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga

Explain how the atom is electrically neutral, having an equal number of protons and electrons.
lord [1]

Answer:

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 and atom become neutral.

Explanation:

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 and atom become neutral. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

For example

The carbon have six protons and six neutrons so its atomic mass is 12 amu and atomic number is six.
