What does it mean to say an element has an oxidation number of 2?
An oxidation number of 2 means the element has lost or gained 2 electrons in a chemical compound. The oxidation number is a measure of the element's ability to combine with other elements.
What happens if you change the number of protons of an element?
The element transforms itself into another element because each element have a specific number of protons. If the number of protons changes, the element changes as well. The number of protons in an atom defines it elemental identity, so if the number of protons in an element increases by one it becomes another element.

How easy or quickly an element combines with other substances?
This is determined by the element's reactivity. Elements that are highly reactive will easily combine with other substances, while elements with low reactivity will combine more slowly or require specific conditions to react. Reactivity is based on the element's position on the periodic table and the number of electrons in its outer shell.
What is the maximum number of covalent bonds an element with atomic number 7 can make with an element with atomic number of 16?
An element with atomic number 7 (nitrogen) can make a maximum of 3 covalent bonds, while an element with atomic number 16 (sulfur) can make a maximum of 2 covalent bonds. Therefore, when they combine, they can form a total of 5 covalent bonds between them.
The term element refers to atoms that have the same number of?
protons in the nucleus. This number is known as the atomic number and distinguishes one element from another. Elements are organized on the periodic table based on their atomic number.
What does it mean to say an element has an oxidation number of 2?
An oxidation number of 2 means the element has lost or gained 2 electrons in a chemical compound. The oxidation number is a measure of the element's ability to combine with other elements.
If element A has a valance number of 3 and element B has a valence number of 2 If you combine them both what formula for the resulting compound be of subscript number of element B?
The chemical formula will be A2B3.
What distinguishes one element from?
An element's atomic number, or number of protons, differentiates one element from another.
What does the oxidation number of an element tell you?
The oxidation number tells you the "combining power" of that element. For example, if Cu has a 1+ oxidation number then it will combine with Cl in a 1:1 ratio, and result in CuCl. If Cu has an oxidation number of 2+, then it will combine with Cl in a 1:2 ratio, and result in CuCl2.
What is the atomic number a measure of?
The atomic number is a measure of the number of protons in an atom's nucleus. It determines the element's identity on the periodic table.
What is a valencie?
The combining power of an element, esp. as measured by the number of hydrogen atoms it can displace or combine with.
What is the known as valency?
It is combining capacity of an atom of an element and is numerically equal to the number of hydrogen atoms or number of chlorine atoms or double the number of oxygen atoms with which one atom of the element can combine.
What part of an element determines its ability to combine with other elements?
The number of valence electrons an element atom contains will determine its chemical properties.
What does each atom have a unique number?
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
What is atomic number and how is it used to distinguished one element from another?
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.
What is atomic number how is used to distinguish one element from another?
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.
