What determines how and atom reacts with different atoms?

The distribution of electrons determines an atom’s chemical properties and how they will react with other atoms. It’s determined by how many additional electrons are needed to fill the valence shell.

What causes atoms to react with each other?

Whatever it takes, they want to attain its configuration they simiply do so by reacting with other elements. Atoms interact with one another by transferring or sharing electrons that are furthest from the nucleus. These outer electrons govern the chemical properties of the element.

What determines how atoms and molecules are structured?

Electrostatic forces hold atoms together in molecules—like the two hydrogen atoms held together in H2 gas. Electrostatic forces also hold electrons and protons together in the atom. The attraction between negatively charged electrons and positively charged protons in an atom give the atom its structure.

Which part of an atom determines the identity of an atom?

number of protons
Explanation: The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes.

Why must atoms react to become stable?

Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons). Energy is required for the chemical reaction to bond atoms. This energy becomes potential chemical energy that is stored in a molecule or chemical compound.

What makes one atom different from another?

The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number. All the elements in the universe are arranged according to their atomic number in the periodic table.

Can elements be made up of molecules?

Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8).

What is the one thing that determines the identity of an atom quizlet?

The identity of the atom is determined by the number of protons; an atom with five protons has different properties than an atom with six protons. small mass. We use a very small unit of mass to measure them, and this unit is called an atomic mass unit (amu).

Which of the three subatomic particles determines the identity of an atom?

The identity of the element is determined by the number of protons, which are positively charged, massive nuclear particles. The number of protons in a nucleus is given by Z , the atomic number.

What 3 ways can atoms become chemically stable?

It’s because they are trying to reach the most stable (lowest-energy) state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons)….There are three major chemical bonds.

• Ionic bond.
• Covalent bond.
• Hydrogen bond.

What determines the way that a particular atom reacts?

What determines the way that a particular atom reacts is the amount of valence electrons it has. Valence electrons are electrons that spend most of their time in the outermost energy level of whatever atom you are studying.

What determines the number of valence electrons an atom has?

Another thing that determines how an atom reacts, coupled with the number of valence electrons it has, is the electronegativity of that atom, or how much it wants to bring electrons to fill its outermost shell. The goal of an atom when it reacts is to have it outermost shell (its valence shell)…

How does the number of electrons in the outer shell affect reactivity?

An atom’s reactivity is determined by the number of electrons in its outermost shell. Because the outer shell can hold up to eight electrons and not all elements are able to fill these shells to capacity, the fullness of the shells will determine the volatility of the atom’s reactive properties as a result…

Why are some elements more reactive than others?

Atoms with high reactivity have outer shells that are imbalanced because of a low number of electrons (one or two) or a higher but not full number (six or seven). The most highly reactive elements are halogens, which are looking to gain one more electron, and alkali metals, which are looking to lose the single electron in their outer shells.
