what do an atom ion and isotope of an element have in common?
An atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.
WHAT IS AN ION AND ISOTOPE?An ion is a charged atom while an isotope is the atoms of an element with the same atomic number but different atomic mass.
For example; Mg2+ is the ionic form of Magnesium while C-12 and C-14 are isotopes of carbon.
Here the ion of an atom will have a different charge but the same mass.
Also The isotope of an atom will have a different mass.
The number of protons V/S the more general atom, an ion has a different number of electrons, and an isotope, a different number of neutrons.
Hence atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.

Potassium iodide is an ionic compound.
Describe what happens, in terms of electron loss and gain, when a potassium atom reacts
with an iodine atom.
Answer:
In this reaction, potassium atoms lose electrons to form positively-charged potassium ions (oxidation) and iodine atoms gain electrons to form negatively-charged iodide ions (reduction).
Explanation:
pls mark as brainliest
In this process, iodine atoms get electrons to produce negatively charged iodide ions, whereas potassium atoms lose electrons to form positively charged potassium ions. Oxidation and reduction takes place.
What is oxidation ?Redox reactions include a change in the oxidation state of the substrate. Similar to how reduction is the acquisition of electrons while oxidation is the loss of electrons or an increase in the oxidation state.
An oxidation process takes place when oxygen interacts with a substance or an element. Another way to think of oxidation is as the process of removing hydrogen from the species of reactants. Molecule, atom, or ion oxidation is the process of losing electrons.
Because they generate new functional groups in molecules or alter existing functional groups, oxidation processes are crucial in the synthesis of organic substances.
Thus, the iodine atom also experiences a change. The iodide atom gets one electron during the reaction with potassium, leaving it with eight electrons at its outer energy level.

Is carbon mixed with sand a homogeneous or heterogeneous mixture
Answer:
homogeneous
Explanation:
because I said so
A carbon mixed with sand is a heterogenous mixture.
What is heterogenous mixture?
Mixture is defined as a combination to two or more simpler substances.
There are two types of mixture
Homogenous mixture - A homogenous mixture is defined as a mixture of two or more component which is uniform throughout the mixture. They include water, air, steel etc.Heterogenous mixture - A heterogenous mixture is defined as a mixture of two or more phase which is not uniform throughout the mixture. They include sand and water, salt and oil etc. They are a non uniform mixture with visible or invisible particles.Thus, carbon mixed with sand is a heterogenous mixture.

What are the rules for naming binary compounds that are formed between nonmetals. Are these compounds ionic compounds or covalent compounds, explain why?
Answer:
Explanation:Compounds between Nonmetals and Nonmetals
Compounds that consist of a nonmetal bonded to a nonmetal are commonly known as Molecular Compounds, where the element with the positive oxidation state is written first. In many cases, nonmetals form more than one binary compound, so prefixes are used to distinguish them.
# of Atoms 1 2 3 4 5 6 7 8 9 10

1.5 of potassium ioxcide in 150cm^3 of solution
Answer:
Explanation:
I'm not sure what is being asked, not the units of "1.5." I don't know of potassium "ioxicide." Was "dioxide" intended?
I'll assume the question is "What is the concentration, in Molar, of 1.5g of potassium dioxide in 150cm^3 of water (150cm^3 is 150 ml).
The molar mass of K2O, potassium dioxide, is 94.2 g/mole. 1.5g is (1.5g/94.2 g/mole) or 0.0159 moles of K2O. The definition of Molar is moles/liter. So take the moles of K2O and divide by the liters, which is 0.150L in this case.
(0.0159 moles K2)/0.150 L = 0.106 M K2O
