Why are some isotopes radioactive and some are not?
Answer: there are atoms that either have too many or too few neutrons or protons in their nuclei. This results in an imbalance between the jedi forces holding them together, which leads to an excess of internal energy. Such atoms are said to be unstable or radioactive.
Explanation:
Thermal radiation emitted by objects allows us to feel infrared
energy as _____
Answer:
THERMAL IMAGING
We can sense some infrared energy as heat. Some objects are so hot they also emit visible light—such as a fire does. Other objects, such as humans, are not as hot and only emit only infrared waves.
How do protons, neutrons, and electrons differ in terms of their electrical charges and
locations within the atom?
Answer:
Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge. ... Electrons are electrochemically negatively charged particles that move random around the nucleus
Explanation:
Protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus.
Explanation:
Atom is defined as the smallest unit of a matter.It consists of three subatomic particles: protons, neutrons, electrons.Protons and neutrons are located inside the nucleus. They are also known as nucleonsElectrons are located outside the nucleus.Protons carry a positive charge, electrons carry a negative charge, and neutrons carry no charge (neutral).So from this, we conclude that the protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus

Hail is an example of which type of phase change?
A) Sublimation
B) Evaporation
C) Condensation
D) Freezing
Answer:
D) freezing
Explanation:Because hail sounds like it is hard and hail comes down and it hurts because it is freezing.
The hail can be defined as the conversion of the water to the ice. Thus, hail is an example of freezing.
What is phase change?The phase can be defined as the state of the matter. With the change in the temperature and the pressure values, the state of the matter, or the phase changes.
The hail has been the solid precipitation of the rain water. With the lowering of the temperature to the critical pressure, the water converts to ice.
The conversion of water to ice has been termed as freezing, Thus, hail is an example of freezing. Hence, option D is correct.

The MSDS for benzene indicates that it is a clear liquid that has a substantial vapor pressure. It has a health rating of
2, a fire rating of 3, and a reactivity rating of 0. It is a cancer-causing agent.
Based on this information, which siatement about benzene is accurate?
Benzene readily reacts with moist air.
Benzene explodes if the container is shaken.
Benzene must be kept away from flames.
Benzene must be stored under high pressure.
Based on the provided information, the statement that is accurate about benzene is that it must be kept away from flames. This is because benzene has a high flammability rating of 3, which indicates that it can ignite and burn easily.
Additionally, the MSDS states that benzene has a substantial vapor pressure, which means it can easily evaporate into the air and form flammable mixtures with air.
The other statements are not accurate. Benzene does not readily react with moist air or explode if the container is shaken. It also does not need to be stored under high pressure. However, benzene is a cancer-causing agent, so it is important to handle it with care and follow proper safety precautions.

Why do atoms always contain the same number of electrons and protons?
Answer:
An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.
Answer:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.

The gas carbon dioxide is a pure substance. Which of the following is true about carbon dioxide?
Answer:
the answer is A :)
Explanation:
describe how changing the particles changed the atom
Changing the particles changes the atoms by converting it to a new substance through bond change.
During a chemical reaction changes occurs in the atoms of an element due to the formation or breaking of bonds.
There is either loss or gain or sharing of atoms between two elements reacting together.
Bonds between atoms break and new ones form and energy is either given out or taken in.
This type of reaction leads to the formation of new substances made up of a new combination of atoms and a different configuration of electrons.
Therefore, because various changes occurs during a chemical reaction, changing the particles changes the atoms by converting it to a new substance through bond change.

yo someone please help meee The density of silver is 10.5 g/cm3. What is the mass (in kilograms) of a cube of silver that measures 0.69 m on each side?
Mass of the cube of silver is 3,449.34 kg
First find the volume of the cube in centimeters because the density is in centimeters:
0.69 * 100 = 69 centimeters
Volume = Side * Side * Side
= 0.69 x 0.69 x 0.69
= 328,509 cm³
The density of a material is calculated by the formula:
= Mass / Volume
As you have the density already and the volume, you can get the mass:
10.5 = Mass / 328,509
Mass = 10.5 * 328,509
= 3,449,344.50 grams
A kilogram is 1,000 grams so the mass in kg is:
= 3,449,344.50 / 1,000
= 3,449.3445 kilograms
