Answer:
Two non bonded electron pairs and four bonded electron pairs
Explanation:
An image of the compound as obtained from chemlibretext is attached to this answer.
The ion ICl4- ion, is an AX4E2 ion. This implies that there are four bond pairs and two lone pairs of electrons. As expected, the shape of the ion is square planar since the lone pairs are found above and below the plane of the square. This is clear from the image attached.
Answer:
Phosphorus-28 undergoes beta-minus decay to produce
Explanation:
In simple words, when a nucleus undergoes beta-minus decay, a neutron is converted to a proton. An electron and an electron antineutrino will be released.
.
One way to tell whether a neutron is converted to a proton, but not vice versa, is to check the sum charges on the two sides of this equation.
The charges on the two sides of this equation is the same. Hence this nuclear equation is possible (but not necessarily correct; however, if the proton and the neutron are in the wrong place the charge won't even be the same.)
Since the mass number of a proton and a neutron are both 1, the overall mass number of the atom will stay the same.
The atomic number is the number of protons in each atom. That number determines the symbol and the chemical properties of the atom. When one neutron in an atom is converted to a proton, the atomic number of the atom will increase by 1.
The atomic number of the daughter nucleus, silicon, is 14. It takes a parent nucleus with atomic number to produce a silicon atom. Refer to a modern periodic table. Atomic number
corresponds to the element aluminum.
Also, the mass number of the daughter nucleus is 28. Since the mass number would stay the same in a beta decay, the mass number of the parent nucleus would also be 28. In other words, it takes an aluminum-28 atom to undergo beta-decay to produce a silicon-28 atom.
