The table compares some characteristics of two atoms.

1 answer:

7 0

The number of protons in X would be 6 while that of Y would also be 6. Thus, the two atoms would be isotopes of the same element.

<h3>Atomic properties of atoms</h3>

The mass number of an atom is the sum of protons and neutrons present in the atom.

For X with mass number 12 and neutron number 6, the number of protons would be:

12 - 6 = 6 protons

For Y with mass number 13 and neutron number 7, the number of protons would be:

13 - 7 = 6 protons.

Thus, both atoms have the same number of protons, meaning that they are likely isotopes of the same element.

Identify the quantum numbers for the electron gained when an F2 ion becomes an F3 ion

zhuklara [117]

Answer: n= 3, l= 0 , m= 0 and s=[/tex]\frac{-1}{2}[/tex]

Explanation:

Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic quantum number : It describes the orientation of the orbital. It is represented as 'm'. The value of m ranges from -l to +l.

Spin quantum number: It describes the spin of the electron. It is represented as 's'. The value of s can be +1/2 or -1/2

$F^{2-}:11: 1s^22s^22p^63s^1$

$F^{3-}:12:1s^22s^22p^63s^2$

Thus electron enters 3s orbital , thus n= 3, l= 0 , m= 0 and s=[/tex]\frac{-1}{2}[/tex]

butalik [34]

Answer:

B. The energy absorbed in the first move is greater than the energy released in the second move.

Explanation:

It takes large amounts of energy for a electron to jump energy levels and the further it moves, the more it takes.

Dafna11 [192]

Answer:

a) specifies the 3-D shape of the orbital

Explanation:

To determine the region where is more probable to find the electron, it is characterized by four quantum numbers:

- Principal quantum number (n): represents the level, or shell, where the electron is. It varies from 1 to 7, and are represented by the letters K, L, M, N, O, P, and Q.

-Azimuthal quantum number (l): represents the sublevel, or subshell. Is represented by the letters s, p, d, f, g, ... And by the numbers 0, 1, 2, 3, ... Each one has a 3-D shape, the s, for example, has a spherical shape.

-Magnetic quantum number (ml): represents the orbital inside the subshell, and varies from -l to +l, passing by the 0. Each orbital can have at least 2 electrons.

-Spin quantum number (ms): represents the spin of the electron, which can be +1/2 or -1/2.
