<u>Answer 45 :</u> This statement is true.

Explanation :

We are taking an example of carbon (C) with atomic number 6 and atomic mass 12.

As we know that the number of protons and number of electrons are equal to the atomic number.

The atomic number of carbon is 6. So, the number of protons and the number of electrons is equal to 6.

And, the number of neutrons = Atomic mass - Atomic number = 12 - 6 = 6

Hence, this statement is true.

<u>Answer 46 :</u> This statement is true.

Explanation :

We are taking an example of oxygen (O) with atomic number 8.

The electronic configuration of oxygen (O) will be,

1s^22s^22p^4

Now we have to calculate the number of electrons from the electronic configuration.

The number of electrons = 2 + 2 + 4 = 8

Hence, this statement is true.

<h2>Answer 1:</h2>

<u>The statement is</u><u> True</u>

<h2>Explanation:</h2>

The number of electrons and protons in any element are the same. Atom as a whole is a neutral particle. Protons are positively charged while electrons are negatively charged. In order to keep the level balanced and keep the atom neutral the net charge must be zero therefore protons and electrons must be the same in order to keep an atom neutral.

<h2>Answer 2:</h2>

<u>The statement is </u><u>True</u>

<h2>Explanation:</h2>

Electron configuration is the distribution of electrons of an atom or molecule or other physical structure in atomic or molecular orbitals. The number of electrons in any particular shell or orbit can be found by the formula 2n² where n is the number of shell. In order to check whether the number of electrons are the same as the electronic configuration, we must see the atomic number because atomic number shows us the total number of electrons in any atom.

Hi there! :)

Both are compounds.

CO_{2} contains 1 carbon (C) atom and 2 oxygen (O)  atoms.

It contains two different elements, so it is a COMPOUND.

Na_{2} O is an IONIC compound with elements Sodium (Na) and Oxygen (O), which are different elements. Therefore, it is also a COMPOUND.
