When all atoms in a substance are alike the substance is a?
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.
What is a unique substance composed of atoms have the same atomic number?
An element is a unique substance composed of atoms with the same atomic number, meaning they have the same number of protons in their nucleus. Each element is distinguished by its atomic number, which determines its position on the periodic table and its chemical properties.
How many electrons are outside the nucleus?
The number of electrons outside the nucleus depends on the atomic number of the element. For neutral atoms, the number of electrons is equal to the number of protons in the nucleus to maintain a balanced charge.
What is the oxidation number if an element?
The oxidation number of an element is the charge that the atom would have if the compound was composed of ions. It can be determined based on the number of valence electrons an element has and the typical charges it tends to form in compounds.
What is the element that gold is made of?
Gold is an element. As such, it is composed of atoms of gold, which in turn are composed of protons, neutrons, and electrons.
When all atoms in a substance are alike the substance is a?
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.
What is a unique substance composed of atoms have the same atomic number?
An element is a unique substance composed of atoms with the same atomic number, meaning they have the same number of protons in their nucleus. Each element is distinguished by its atomic number, which determines its position on the periodic table and its chemical properties.
What does each different element represents?
an atom with a specific number of electrons { S.L.K ALL DAY} Each element is a pure substance composed of atoms which contain the same number of protons, which is the atomic number. The number of protons and atomic number are unique to each different element.
an element is a substance composed of atoms that all have the same number of protons.True or false?
True apex
A substance whose atoms all contain the same number of protons and the same number of electrons are?
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
How many electrons are outside the nucleus?
The number of electrons outside the nucleus depends on the atomic number of the element. For neutral atoms, the number of electrons is equal to the number of protons in the nucleus to maintain a balanced charge.
What is the oxidation number if an element?
The oxidation number of an element is the charge that the atom would have if the compound was composed of ions. It can be determined based on the number of valence electrons an element has and the typical charges it tends to form in compounds.
What is a pure substance composed of atoms with the same number of protons and cant be broken down?
A chemical element.
What is the element that gold is made of?
Gold is an element. As such, it is composed of atoms of gold, which in turn are composed of protons, neutrons, and electrons.
What is a unique subtance composed of atoms having the same atomic number?
A element is a unique substance that is composed of atoms having the same atomic number. Energy is the ability to do work.
Is nickel a pure substance or a mixture?
Nickel is a chemical element, and as such, it is a pure substance.
What are elements composed of?
Elements are composed of atoms, which are made up of protons, neutrons, and electrons. Protons and neutrons make up the nucleus of an atom, while electrons orbit around the nucleus. The specific number of protons in the nucleus determines the element's identity on the periodic table.
