True or false Every atom of the same element has the same atomic number.

Chemistry
1 answer:
Veseljchak [2.6K]3 years ago
4 0

Answer: True

Explanation: Every atom of the same element has the same atomic number of number of protons in its core. This is why chemists say that an atom is defined by its atomic number of the number of protons.

Unlike neutrons and electrons, you can't change protons. You can change the number of neutrons and it will still be the same element, but one is going to be a little bit heavier or a little bit lighter than another.

In addition, you can change electrons which creates

ions or charged atoms.

However, you can't change the protons.

For example, hydrogen has 1 proton in its nucleus no matter what and helium has 2 protons in its nucleus no matter what and so on.

can a light object that was hit with a small force accelerate as rapidly as a heavier object hit with a big force? why or why no
Tcecarenko [31]

The acceleration is defined by force divided by the mass of the object. So, When the smaller object is hit by a small force, it can produce equal acceleration which is same as that of the bigger body hit with large force.

<h3><u>Explanation:</u></h3>

Force is defined as the product of the mass of the body its applied to and the acceleration of the body in the direction of the force. So acceleration is force divided by the mass of the body.

Let the mass of the smaller body be m and that of the larger body be M.

The smaller force applied on the smaller body be f and the larger force applied on the larger body be F.

So acceleration of the larger body = F/M.

Acceleration of the smaller body = f/m.

For the accelerations to be same,

F/M = f/m.

Or F/f = M/m.

So when the ratio of the force applied on two bodies is in ratio of their masses, the acceleration becomes equal.

What are isoelectronic and isostructural species?
alexgriva [62]
Isoelectronic species are ions or elements that have equal number of electrons. From the root word, electron of the word isoelectronic. On the other hand, isotructural species are compounds with the same structures.Hope this answers the question.

The prefix mili-means a thousand
OLEGan [10]
<h2>Answer:</h2>

<em>Given data:</em>

1 kilogram = 1,000 grams

how many kilograms is 1,216 grams?

<em>Solution:</em>

1000 grams = 1 kilogram

1 gram = 1/1000 kilograms

1216 grams = 1/1000 * 1216 = 1.216 kilograms.

                                                    <em> Hence 1216 grams =  1.216 kilograms.</em>
