Answer:

This question is incomplete but the completed question is below

In which of the following are the symbol and name for the ion given correctly?

a. Fe2+: ferrous ion; Fe3+: ferric ion

b. Sn2+: stannic ion; Sn4+: stannous ion

c. Co2+: cobalt(II) ion; Co3+: cobaltous ion

d. Pb2+: lead ion; Pb4+: lead(IV) ion

The correct option is a

Explanation:

In this question, the knowledge of ion naming is been tested. Below, the ions and there correct names will be presented

Pb2+ is lead (II) ion

Pb4+ is lead (IV) ion

Co2+ is cobalt (II) ion and it is also called cobaltous ion

Co3+ is cobalt (III) ion

Sn2+ is tin (II) ion and it is also called stannous ion

Sn4+ is tin (IV) ion and it is also called stannic ion

Fe2+ is iron (II) ion and it is also called ferrous ion

Fe3+ is iron (III) ion and it is also called ferric ion

From the above, we can deduce that option a is the one that has it's symbol correctly attached to it's name

Given mass=1.3g
Atomic mass=65u

Molar mass=65g/mol

Now

$\boxed{\sf No\:of\:moles=\dfrac{Given\:Mass}{Molar\:Mass}}$

$\\ \rm\longmapsto No\:of\;Moles=\dfrac{1.3}{65}=0.02mol$

How does the electron configuration of elements within the same group compare? (A.) They all have their valence electrons in the

lesya [120]

Answer:

B.They all have their valence electrons in the same type of subshell

Explanation:

The electron configurations of elements in the same group (column) of the periodic table have them in the same type of subshell.
But the subshells may be of different shells. Thus , the energies of them need not be the same.
For example , The Alkalai Metals are found in the first column of the periodic table Group IA. This set of elements all have valence electrons in only the ' $s$ ' orbital and because they are in the first column they all have $s^{1}$ configuration. i.e,

H $1s^1$
Li $1s^2 2s^1$
Na $1s^2 2s^2 2p^6 3s^1$
K $1s^2 2s^2 2p^6 3s^2 3p^64s^1$
