3 0

Given :

An atom Iodine.

To Find :

How many electrons will an iodine atom donate or accept, based on its number of valence electrons :

A.donate seven electrons

B.accept one electron

C.donate one electron

D.accept seven electrons

Solution :

We know, valence electron in Iodine is 7 electrons.

So, it is easy for iodine to accept 1 electron rather than giving all 7 electrons to another element.

Therefore, Iodine will accept one electron ( Option B.).

Hence, this is the required solution.

The atomic mass of helium-4 is 4.0026 amu. How many of each
umka21 [38]

Answer:

Protons: 2.

Electrons: 2.

Neutrons: 2.

Explanation:

Hello,

In this case, since an atom's atomic number is equal to the number of electrons, considering the electron configurations, taking into account that helium-4 is neither positively nor negatively charged, we can infer that the number of electrons equal the number of protons, which in this case are 2, due to the fact that is atomic number is 2.

Moreover, as helium-4's atomic number is 4 as a whole number, we compute the number of neutrons by using the shown below equation:

Neutrons=mass\ number-atomic\ number\\\\Neutrons=4-2\\\\Neutrons=2

Regards.
