One of the following is not true about Democritus.

. Option A is correct. Different samples of any compound have the same elements in the same proportion. This is because atoms accept electrons or donate electrons to form stable octet fulfilled electronic configurations and this is only possible by formation of molecules.

They have a nucleus that always remains the same. All ordinary substances are made of atoms. Atoms are the basic units from which molecules and ions are formedC.

Atoms are not able to exist independentlyB. The atoms of only noble gases are chemically uncreative and exist in free state. All known substances are made of molecules.

Which of the following statements is not true about an atom A. Which of the following statement is not true about an atom1atoms are not able to exist independently2atoms are the basic units from which molecules and ions are formed3atoms are always neutral in nature. So atoms cannot exist along.

Because all elements are made of atoms they even composed by molecules there extremely small and when two or more atoms combine they create molecules thats why they are all true no false. When atoms are changed into other atoms it is not a chemical change but a nuclear change. CAtoms are the tiny building blocks of matter.

The nucleus of an atom has a positive charge. They give off smaller particles as they fall apart. He suggested that atoms were the basic units of matter.

64 Which of the following is NOT true about molecules. See what the community says and unlock a badge. The number of atoms in 1 mole of carbon equals the number of atoms in 1 mole of boron is false because the molar mass of carbon is different from that of boron.

Atoms may be joined together in well-defined molecules. Atoms are mostly empty space. These elements are also known as the inert gases.

Atoms usually exist in the two forms i molecules and ii ions Therefore atoms are the basic unit from which molecules and ions are formed. AAtoms are made up of smaller particles BAtoms are the basic unit of life. They are extremely small.

Atoms are always joined directly to other atoms. They all have 6 protons. The elements in Group 18 of the periodic table are known as noble gases.

All the elements on the far right side of the periodic table inert or noble gas atoms can exist independently because they all fulfil the octet rule. Which of the following is NOT TRUE about atoms. Atoms of isotopes of an element have different numbers of protons.

E They all have 7 electrons. A Atoms are not able to exist independently. O They all have the same atomic number.

Option B is true. His approach was philosophical not experimental. They give off energy as they fall apart.

They all have the same mass number. A chemical reaction is a process where one or more substances molecules or atoms combine or breakdown into new or different substances not other atoms. They do not need bond to become stable.

Atoms may be arranged in repeating crystal patterns. But only inert gases already have octet fulfilled configurations so they can exist as atoms. Atoms of the same element can have different masses.

Moles MassMolar mass. Which of the following statements is not true. They are composed of molecules.

Which of the following statements about atoms are true. It is not true that atoms cannot exist independently. 5 points A Atoms are connected via their electrons.

C They all have the same atomic number. B They are isotopes. The number of moles of an element is expressed as the ratio of the mass of the substance to its molar mass.

B All atoms in a molecule have complete outer shells. Correct option is A Option A is false. Which of the following is not true for the atoms 13N 14N and 15N.

He was a Greek philosopher. D They all have 7 protons. They are radioactive c.

They can combine with other atoms. Atoms can not exist independently. Atoms are not able to exist independently is not true Atoms of most elements are not able to exist independently but inert gases can exists as atoms.

The neutrons do not affect how the atom interacts with other atoms but they do have an effect on the mass and stability of the nucleus. O O They all have 6 electrons. Atoms of most elements cannot exist independently although inert gases can exist as atoms.

Atoms of most of the elements are chemically very reactive and do not exist in the free state. 7 If sodium contains 11 electrons in what order do. Carbon atomic number 6 has electronic configuration 1s 22s 22p 4 It has 4 valence electrons which are shared with other atoms to form 4 covalent bonds.

Atoms are always neutral in natureD. C The number of protons changes when atoms form a molecule. A They all have the same mass number.

D Uncharged atoms are less stable than the molecules they form when combined. Which of the following is NOT true of atoms. Which of the following is NOT true of compounds.

They make up elements. Which of the following is NOT true about unstable atoms. The unique set of properties of a compound differ from the properties of the elements that make up the compound.

Atoms are not able to exist independently. Correct option is B Carbon atoms form 4 covalent bonds. His ideas were quickly accepted.

Atoms aggregate in large numbers to form the matter that we can see feel or touch Snapsolve.
