In some atoms<span>, the required energy is not sturdy enough to hold the </span>nucleus<span> together, and the </span>nuclei<span> of these </span>atoms<span> are said to be </span>fractionable<span>. </span>Weak atoms will<span> lose neutrons and protons as they attempt to become </span>stable<span>. In this way, atoms need that required energy.

Answer:

A stable atom is an atom that has enough binding energy to hold the nucleus together permanently. An unstable atom does not have enough binding energy to hold the nucleus together permanently and is called a radioactive atom.

A 253 g block of wood has the following dimensions: Length 15.24 cm Width 6.64 cm Height 3.56 cm What is the density of the wood
yanalaym [24]

Answer:

0.7 g/cm³

Explanation:

<em>hey there,</em>

<em />

< The formula for density is p = \frac{m}{v}  where m = mass, v = volume, and p = density. An easy way to remember the formula is density equals love. I found this easy to remember because p = ♡ and when you think about it, if you split the heart in half through the middle like a fraction, it will make \frac{m}{v} (if you don't understand what I'm saying, try writing it out and you will be able to see what I'm talking about!)

We already know that the block is 253 g so the mass is 253 g.

To find the volume, always multiply the 3 values width, length, and height whenever you are trying to find the volume of a block.

15.24 cm x 6.64 cm x 3.56 cm = 360.25 cm³

Now plug it into the formula.p = \frac{m}{v}=\frac{253}{360.25} = 0.7 g/cm³ >

<u>Hope this helped! Feel free to ask anything else.</u>
