Answer:

The atomic radius (r) of an atom can be defined as one half the distance (d) between two nuclei in a diatomic molecule. Atomic radii have been measured for elements. The units for atomic radii are picometers, equal to 10−12 meters

Write the Iconic Bond to Metals

Nutka1998 [239]

<u>Answer:</u> The ionic compound formed is magnesium chloride having formula $MgCl_2$

<u>Explanation:</u>

Ionic compound is defined as the compound which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

Magnesium is the 12th element of the periodic table having electronic configuration of $1s^22s^22p^63s^2$

This element will loose 2 electrons to form $Mg^{2+}$ ion

Chlorine is the 17th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^5$

This element will gain 1 electron to form $Cl^{-}$ ion

So, for every 1 atom of magnesium, 2 atoms of chlorine are required. Thus, the chemical formula becomes $MgCl_2$

Hence, the ionic compound formed is magnesium chloride having formula $MgCl_2$

A chemist measures the amount of bromine liquid produced during an experiment. She finds that 14.4 g of of bromine liquid is pro

Alex787 [66]

Answer:

0.09 moles of Br₂

Explanation:

Bromine liquid it refers at Br₂ molecule which is liquid at room temperature.

Now to calculate the number of moles we use the following formula:

number of moles = mass (g) / molecular mass (g/mol)

For Br₂ molecule we have:

number of moles = 14.4 / 160 = 0.09 moles of Br₂

A 50 gram sample of a radioisotope undergoes 2 half-lives. How many grams

Veseljchak [2.6K]

Answer:

At the end of second half life 12.5 g will left

Explanation:

Given data:

Total Mass = 50 g

Half lives = 2

Mass remain at the end = ?

Solution:

At time zero = 50 g

At 1st half life = 50 g /2 = 25 g

At second half life = 25 g/2 = 12.5 g

So at the end of second half life 12.5 g will left.
