Answer:
same number of protons as electrons
Explanation:
The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element. ... If you change the number of electrons in an atom, you will get an ion of the element.
b) compound
c) isotope
d) proton
e) molecule
Answer:
A
Explanation:
An element is a substance that cannot be broken down into simpler substances using ordinary chemical procedures. To disintegrate an element, procedures like nuclear reactions needed to be used.
In fact, it was thought of that the elements are indivisible during the days of Dalton, but advances in science and technology has shown that these elements could be broken down albeit not easily
An element is a substance that cannot be broken down into other substances by ordinary chemical methods. It is the basic unit of all matter. Examples of elements include gold, silver, and carbon.
A substance that cannot be broken down into other substances by ordinary chemical methods is called an element. This is because elements are the fundamental materials of which all matter is composed. For instance, gold, silver, and carbon are examples of elements. Unlike compounds, isotopes or molecules, an element is made up of the same type of atom and cannot be decomposed into simpler substances by any ordinary chemical processes.

Hydrogen is being oxidized in the given reaction CO2 + H2 → CO + H2O. the carbon atom in CO2 is reduced to CO, while the hydrogen atoms in H2 are oxidized to H2O.
Oxidation is the loss of electrons, while reduction is the gain of electrons. To determine which class is being oxidized and that is being diminished, we can equate the oxidation states of the materials in the reactants and produce.
In CO2, the element atom has an oxidation state of +4, while the oxygen atoms each have an disintegration state of -2. In H2, each hydrogen atom has an decay state of 0.
In CO, the element atom has an oxidation state of +2, while the oxygen dot in H2O has an oxidation state of -2. The hydrogen atoms in H2O each have an disintegration state of +1.
Therefore, the carbon atom in CO2 is decreased to CO, while the hydrogen atoms in H2 are oxidized to H2O.
