MATTER
What are the three states of matter?
Liquid,Solid,Gas
What makes an atom?
It is composed of protons, neutrons, and electrons.
What is the symbol for the element with atomic number 1?
The symbol for the element with atomic number 1 is H, which stands for hydrogen.
What is ionic bonding?
lonic bonding is a type of chemical bonding where electrons are transferred between atoms.
How are covalent bonds formed?
Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration.
how many major properties are in matter? What are the major properties?
There are 4 major properties in matter
The four major properties of matter are called Chemical properties, physical properties, extensive properties and intensive properties
What are isotopes?
An isotope is an atom of the same protons with a different number of neutrons.
What is the lightest element on the periodic table?
Hydrogen (H) is the lightest element on the periodic table.
How are cations formed?
Cations are formed when an atom loses one or more electrons, resulting in a positive charge.
What is a molecule?
A molecule is a group of atoms held together by covalent bonds.
What is the difference between an element and a compound?
Compounds are made up of two or more elements chemically combined, whereas elements are pure substances that cannot be broken down.
What is the atomic number?
The atomic number of an atom represents the number of protons in its nucleus. It determines the element to which the atom belongs.
What is the most reactive group of elements on the periodic table?
The most reactive group of elements on the periodic table is Group 1, also known as the alkali metals.
How are anions formed?
Anions are formed when an atom gains one or more electrons, resulting in a negative charge.
Are covalent bonds stronger or weaker than ionic bonds?
Covalent bonds are generally stronger than ionic bonds
What is the difference between a physical change and a chemical change?
Physical changes involve the change in matter's form or state, while chemical changes alter the substance's properties by forming a new substance.
How does an electron shell work?
A shell of electrons is a level or orbit of energy around the nucleus where electrons are located. In order to determine which shell has the lowest energy, they are organized into different levels of energy.
What element is Silicon (Si)?
The element is called metalloid.
Are ionic bonds strong or weak?
lonic bonds are generally strong bonds
Are covalent compounds usually solid, liquid, or gas at room temperature?
Covalent compounds can exist in any state at room temperature, depending on the specific compound. For example, water is a liquid, while carbon dioxide is a gas.
What is the law of conservation of mass?
A chemical reaction does not create or destroy mass according to the law of conservation of mass. A reaction produces a product whose mass is equal to the total mass of the reactants.
Do ions and atoms differ in any way?
Electrons and protons in an atom are equal, meaning they are electrically neutral. Ions, on the other hand, are atoms that have gained or lost electrons and therefore have positive or negative charges.
Which element has the highest atomic number?
The element with the highest atomic number is Oganesson (Og) with atomic number 118.
What is the overall charge of an ionic compound?
The overall charge of an ionic compound is neutral, as the positive and negative charges of the ions balance each other out.
What is the difference between a single, double, and triple covalent bond?
A single covalent bond involves the sharing of one pair of electrons, a double covalent bond involves the sharing of two pairs of electrons, and a triple covalent bond involves the sharing of three pairs of electrons.
