Answer:
It would be an isotope.
Background Information:
Isotopes are typically elements that have a different number of protons than neutrons. The atomic mass is the total number of protons and neutrons. The atomic number is the number of protons.
Explanation:
If the atomic number is the number of protons that means that this particular element has 8 protons. If the atomic mass is the total number of protons and neutrons then we can simply take away the amount of protons from that number, 18 - 8 = 10. If we take protons away from the number of protons and neutrons we are left with the number of neutrons. So there are 10 neutrons. Because there are 8 protons and 10 neutrons, or a different amount of neutrons and protons we know that this particular atom is an isotope.

can anyone help me with this question. is there anybody who is an expert in science??
Answer:
Explanation:
GIVEN ; FORCE = 2000 NEWTON
DISPLACEMENT = 10 M
TIME = 50 SECONDS
AS WE KNOW , POWER = WORK / TIME
= WORK = FORCE × DISPLACEMENT = 2000 × 10
= 20000 JOULES
THEN, POWER = 20000/ 50
SO, POWER = 400 WATT ( JOULES / SECOND )

A certain solid has a volume of 35.7 cm and weighs 85 grams. What is its density?
Answer:
The answer is 2.38 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of object = 85 g
volume = 35.7 cm³
We have
[tex]density = \frac{85}{35.7} \\ = 2.380952...[/tex]
We have the final answer as
2.38 g/cm³Hope this helps you

Answer:
I looked it up so the answer is for sure A
Explanation:
Select the correct answer. Consider an atom that has an electron in an excited state. The electron falls to a lower energy level. What effect does that have on the electron? A. The electron releases energy in the form of light. B. The electron absorbs energy in the form of light. C. The electron retains its energy without any change. D. The electron transfers its energy to other electrons.
Answer:
A
Explanation:
The more energy u give the more the electron is able to get far away from the nucleas. So the opposite happens when u take away some energy, it will falll on lower energy state and will radiate the energy difference in form of a photon/light.

ethane is a substance that is used when making plastic. a molecule of ethane is made of two carbon atoms and six hydrogen atoms. the carbon atoms are joined by the chemical bond. each of the hydrogen atoms is joined to one of the carbon atoms by a chemical bond. which is an accurate model of ethane?
Help ASAP!!!
Answer:
C
Explanation:
Option C is an accurate model of ethane.
Ethane is an alkane that has two carbon atoms bonded together and each atom has three hydrogen atoms that are attached to them. Ethane has single bonds and that makes it an alkane.
This model of ethane has six carbon-hydrogen bonds shown with solid lines that are protruding out. Rotation that takes place about the carbon-carbon bond actually results in the different molecular conformations of ethane.

what is neons destiny and mohs hardness
The number of electrons in each of Neon's shells is 2, 8 and its electronic configuration is 1s2 2s2 2p6.
...
Neon Properties.
Melting Point: -248.59°C, -415.462°F, 24.56 K
Neon's destiny is to produce vibrant and attractive colors in neon signs, while Mohs hardness is a scale used to measure the hardness of minerals, and it does not apply to the element neon.
Neon's destiny refers to the role or purpose of the element neon in the natural world. Neon is a noble gas that is commonly used in neon signs due to its vibrant red-orange color when electricity is passed through it. Its destiny, in this context, is to create visually appealing and eye-catching signs.
On the other hand, Mohs hardness is a scale that measures the hardness of minerals. It was developed by Friedrich Mohs in 1812. The scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest mineral.
Now, let's discuss the Mohs hardness of neon. Neon is an element, not a mineral, so it does not have a specific Mohs hardness value. The Mohs hardness scale is specifically designed for minerals, not elements. Therefore, we cannot assign a Mohs hardness value to neon.

A sample of phosphorus contains 1.38e24 atoms. How many moles of phosphorus is this?
2.3 grams
0.44 grams
2.3 moles
0.44 moles
Answer:

Which description refers to fog?
burns off when it gets dark
extends up to 10 miles into the sky
is found in areas near bodies of water
forms when the ground warms at night after a cool, dry day
Answer:
The correct option is;
Is found near bodies of water
Explanation:
Fog forms as an aerosol which is visible to the eye that normally consists of tiny condensed water vapor droplets or crystals of ice that is formed when air that is warm comes in contact with cool air close to the Earth's surface. Fog can be taken as a stratus like cloud that lies close to the Earth's surface and it normally forms due to the presence of water bodies that are nearby, the topography of the area or the conditions of the wind.

What needs to be added or taken away to cause a change in state?
Answer:
One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules.
Which of the following statements is true? Atoms of isotopes of an element have different numbers of electrons. Atoms of isotopes of an element have different numbers of neutrons. Atoms of the same element all have the same mass. Atoms of isotopes of an element have different numbers of protons.
Answer:
atoms of isotopes of an element have different numbers of neutrons.
Explanation:
isotopes have the same number of protons, but different numbers of neutrons.
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Atoms of isotopes of an element have different numbers of neutrons.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
One element can have isotopes of its own. Isotopes are the atoms of element with same atomic number but different mass number. Example Hydrogen has three isotopres like hydrogen, deuterium and tritium with mass number 1, 2 and 3 respectively. Atoms of isotopes of an element have different numbers of neutrons.
