What particles are responsible for chemical properties?
I would say proton and electron are the two most important subatomic particles in an atom. The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
Which charged particles are responsible for chemical interactions?
electrons The correct answer is Only electrons participate in chemical reactions. Electrons are the negatively charged particles of an atom that are involved in chemical reactions.
What particle is most involved in chemical reactions?
Electrons (especially valence electrons) are the only subatomic particles which are involved in ordinary chemical changes, and we have spent considerable time describing the rearrangements they undergo when atoms and molecules combine.
What subatomic particle is responsible for the light color produced when certain compounds are burned?
ELECTRONS ELECTRONS CAUSE THE DIFFERENT COLORS THAT ARE OBSERVED WHEN MATERIALS ARE BURNED. ELECTRONS ARE SUBATOMIC PARTICLES THAT MAKE UP ATOMS. WHEN AN ATOM IS HEATED THE ELECTRONS JUMP INTO A HIGHER ENERGY LEVEL.
What is responsible for chemical reactions?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What particle in the atom is responsible for determining the chemical and physical properties of an element?
Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. The chemical properties of the atom are determined by the number of protons, in fact, by the number and arrangement of electrons. The configuration of these electrons follows the principles of quantum mechanics.
Which particles are responsible for the charge of an ion?
Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
Are protons or electrons responsible for chemical reactions?
The electrons are responsible for the actual chemistry happening around an atom, however the number of electrons in an atom is determined by the charge of the nucleus, i.e. by the protons.
What particles in an atom are involved in chemical reactions in nuclear reactions?
Many entities can be involved in nuclear reactions. The most common are protons, neutrons, alpha particles, beta particles, positrons, and gamma rays, as shown in Figure 1.
What is responsible for the colors emitted by elements?
The color of light emitted depends on the energy emitted by each electron returning to its original state. Within the flame, regions of particles with similar energy transitions will create a seemingly continuous band of color.
Why do chemicals burn different colors?
Different chemicals react with fire to produce different colored flames because the electrons moving around the nucleus have different energy levels in each element.
Which of the following process is responsible for chemical change?
The correct answer is Photosynthesis in plants. A chemical change takes place when a substance undergoes a chemical change i.e its molecular composition is changed entirely. It involves the formation of new substances and it is a permanent change.
What subatomic particle is responsible for chemical reactivity of the atom?
1 Answer. Chemical reactivity is governed by the electron, fundamental particles of negligible mass, and negative charge.
Which of the following is responsible for the chemical behavior chemical properties of an element?
valance electrons The electrons in the outermost shell, or valance electrons, tend to be responsible for the chemical behavior of an element.
What part of the atom is responsible in the physical property?
Explanation: The number of electrons, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element.
What particles are responsible for the atomic mass of an element?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons.
Which particles are responsible to determine the charge of atomic nucleus?
While the protons are constrained within the nucleus, held together by neutrons, the electrons orbit the nucleus. These subatomic particles are the reason behind the determination of the mass and charge of the atom.
Which particles are transferred during chemical reaction?
During a chemical reaction, the atoms of the original substances gain, lose or share their electrons with those of the substances with which they are reacting. The reaction creates new substances made up of a new combination of atoms and a different configuration of electrons.
What are nuclear particles?
n. Any of various particles of matter smaller than a hydrogen atom, including the elementary particles and hadrons.
What part of the atom is involved in chemical reactions protons neutrons nucleus electrons?
The part of the atom involved in a chemical reaction is the electron cloud. The electron cloud is the part of the atom surrounding the nucleus….
How do chemicals make colors?
A chemical gets its color by electrons absorbing energy and becoming excited. That excitation absorbs wavelengths of light; what we see is the complementary color of the absorbed wavelengths.
Why do chemicals emit different colors of light?
Every element has a different number of electrons and a different set of energy levels. Thus, each element emits its own set of colours.
What color does gold burn?
Table of Flame Test Colors
| Flame Color | Metal Ion |
|---|---|
| Pale green | Tellurium, antimony |
| Yellow-green | Molybdenum, manganese(II) |
| Bright yellow | Sodium |
| Gold or brownish yellow | Iron(II) |

How do you the designers of fireworks make the explosions have different colors?
They're created by the use of metal salts. These salts are different from table salt, and in chemistry 'salt' refers to any compound that contains metal and non-metal atoms. Some of these compounds produce intense colors when they are burned, which makes them ideal for fireworks.
What causes a chemical reaction?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What are the substances that cause or start chemical reaction?
These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
Which particles are important for how an atom interacts with other atoms and for chemical reactions?
Which parts of atoms can interact (react) to form chemical bonds? valence electrons; Only the outermost parts of atoms interact (react) with each other, and those are the valence electrons.
Which atomic particle most determines the chemical behavior of an atom?
protons Its chemical behavior is determined by the atomic number 2 (the number of protons), which equals the normal number of electrons; the stability of its nucleus (that is, its radioactivity) varies with its atomic weight (approximately equal to the number of protons and neutrons).
What are electrons responsible for?
Electrons play an essential role in numerous physical phenomena, such as electricity, magnetism, chemistry and thermal conductivity, and they also participate in gravitational, electromagnetic and weak interactions.
What are the 3 particles of an atom?
Given that these particles make up atoms, they are often referred to as subatomic particles. There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
