tatyana61 [14]

Answer:

Explanation:

1) alkali metals and halogens as alkalis have 1 electron they need to get rid of in order to gain a full outer shell of electrons and the halogens have to gain 1 electron.

2) they have the same number of electrons on the outer shells

3)they usually have high melting points

4) low or no reactivity

5) group 7

When the u-235 nucleus is struck with a neutron, the zn-72 and sm-160 nuclei are produced, along with some neutrons. How many ne
Oxana [17]

4 neutrons that are produced along with the Zn and sm. The complete final equation is:  ²³⁵U + ¹n → \;^{72}Zn+\;^{160}sm + 4 n

<h3>What atomic mass?</h3>

Atomic mass, the quantity of matter contained in an atom of an element.

1) In the left side of the transmutation equation appears:

²³⁵U + ¹n →

Deleting the atomic number (subscript to the left) because the question does not show them as it is focused on a number of neutrons.

2) The right side of the transmutation equation has:

→ \;^{72}Zn+\;^{160}sm +?

3) The total mass number of the left side is 235 + 1 = 236

4) The total mass number of Zn and sm on the right side is 160 + 72 = 232

5) Then, you are lacking 236 - 232 = 4 unit masses on the right side which are the 4 neutrons that are produced along with the Zn and sm.

The complete final equation is:

²³⁵U + ¹n → \;^{72}Zn+\;^{160}sm + 4 n
