9) A certain atom has 10 electrons, 14 neutrons, and 11 protons. Write the name of this element in isotope notation.​

Chemistry

Dimas [21]3 years ago

Answer:

²⁵₁₁Na⁺

Explanation:

Details about the atom:

          Number of electrons  = 10 electrons

          Number of neutrons  = 14 neutrons

          Number of protons  = 11 protons

The atomic number of an atom is a good indicator of the type of atom we have been given.

From the subatomic particles, the number of protons is the same as the atomic number.

 Since the number of protons is 11, its atomic number will be 11.

The element with atomic number 11 is sodium, Na.

  To write a complete notation, we also need the mass number;

  Mass number  = number of protons + number of neutrons

  Mass number  = 11 + 14  = 25

 The charge on the atom:

     Charge  = Number of protons  - number of electrons  = 11  - 10  = 1+

The element in isotopic notation is given as;

                  ²⁵₁₁Na⁺

Which equation represents a transuranium​
Maksim231197 [3]

Answer:

1) Since you have not provided the equations to select the right one, I am going to explain you the relevant facts that are used to solve this question.

2) The transuranium elements are the chemiical elements with atomic number greater than that of the uranium.

The atomic number of uranium is 92. So, the transuranium elements are the elements with atomic number 93 or greater.

This are some of the transuranium elements:

Neptunio - 93

Plutonium - 94

Americium - 95

Curium - 96

Berkelium - 97

Californium - 98

Einstenium - 99

And so all the known elements (the last one is the 118).

3) In a nuclear reaction the total mass number ( shown as superscript to the left of the symbol) and total atomic number (shown as subscript to the left of the symbol) are conserved.

4) Beta decay is the release of a beta particle, which is an electron (considered massles and with charge - 1). So, the beta decay is represented with the symbol:

0

 β, which means 0 mass and charge - 1.

-1

5) This is, then, an example of a β decay equation for one transuranium element:

239              239            0

     Np    →         Pu   +      β

 93                94            -1

As you see 239 = 239 + 0 and 93 = 94 - 1, showing that the total mass number ( shown as superscript to the left of the symbol) and the total atomic number (shown as subscript to the left of the symbol) are conserved.
