The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as 'isotopes'. While the particular isotope involved does not affect how an atom will react chemically, it does determine how the atom will behave in nuclear reactions.

Answer;
  1. Dalton believed that all atoms of the same element have the same mass. He said that compounds are formed when atoms of more than one element combine. According to Dalton, in a certain compound, the atoms of the compound's elements always combine the same way. In 1827, British scientist Robert Brown looked at pollen grains in water under his.
  2. One mole of atoms of any element always has the same number of atoms (about 6.022 × 10 23). This number was chosen so that if an element has an atomic mass of 1 u, a mole of atoms of that element has a mass close to one gram.
  3. For an element to be 'itself' it MUST have the same number of protons. If the proton number changes, so does the element. For example oxygen always has six protons, if it had one more, it would be nitrogen! (: Electrons can vary, hence charges on ions etc. And when the number of neutrons varies, these are referred to as different isotopes (.

-Protons

All atoms of the same element must have the same number of protons.

Explanation;Atoms are the smallest particles of elements that can take part in a chemical reaction. Atoms are made of sub-atomic particles, namely; electrons found in the energy levels, protons and neutrons which are both found in the nucleus of an atom.Atoms of the same may have different neutrons, forming isotopes, which are atoms of the same element with the same number of protons but different number of neutrons.Atom may also form ions which will have the same number of protons but different number of electrons as the original atom.Therefore, atoms of the same element will always have the same number of protons or atomic number.

Answer;

-Protons

All atoms of the same element must have the same number of protons.

Explanation;

As we know that any atom is represented as

here we have

z = atomic number = number of protons

A = mass number = number of neutron + number of protons

Now if we have atoms of same element then we can say that its atomic number will remain same

This shows that number of protons will not change in that case

So here correct answer will be

PROTONS

Option (b) is the correct answer.

Explanation:

When two atoms of the same element has different number of neutrons but same number of protons then it is known as an isotope.

For example, isotopes of carbon are and .

Also, when two atoms of the same element have same number of protons then their chemical properties remain the same.

Therefore, we can conclude that two atoms of the same element must have the same number of protons.

Protons

Explanation: The number of protons corresponds to the atomic number.

The correct answer is protons.

Explanation:

An ion is formed when an atom looses or gains electron.

When an atom looses electrons, it will form a positive ion known as cation.When an atom gains electrons, it will form a negative ion known as anion.

Atomic number is defined as the number of protons that are present in an atom. It is represented by the symbol 'Z'.

Atomic number = number of protons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom. It is represented by the symbol 'A'.

Mass number = Number of protons + Number of neutron

Each and every element has a unique number known as atomic number and atomic number is number is identified by the number of protons that are present in an atom.

All atoms of the same element has same number of protons. For Example: All atoms of sodium will have 11 number of protons.

Hence, the correct answer is protons.

Explanation:

Atomic number is defined as the total number of protons present in an element.

Each element of the periodic table has different atomic number because each of them have different number of protons.

For example, atomic number of Na is 11, and atomic number of Ca is 20.

On the other hand, atomic mass is the sum of total number of protons and neutrons present in an atom.

For example, atomic mass of nitrogen is 14 that is, it contains 7 protons and 7 neutrons.

Thus, we can conclude that all atoms of the same element must have the same number of protons.

Explanation:

For 4:

A compound is defined as the substance which is formed from the combination of two or more elements in a fixed ratio. They show different properties than the element from which they are formed from. For Example: shows different properties than carbon and oxygen atoms.

Hence, the correct statement is entirely new properties than the elements that composes it.

For 5:

Compounds are formed when two or more atoms of different elements combine chemically. So, the compounds can be separated by any chemical means only.

Hence, the correct answer is chemical means.

For 6:

Atomic number for an element is defined as the number of protons or number of electrons.

Electrons cannot be used to characterize an element.

Atoms that have same number of protons belong to same element and atoms which have different number of protons belong to different element.

Thus, the correct answer is protons.

For 7:

An ionic bond is formed when complete transfer of electrons takes place from one atom to another. An atom which donates electrons is considered as an electronegative atom and the one which accepts electrons is considered as an electropositive element.

The compound formed is an ionic compound. This compound is usually formed when a metal combines with a non-metal.

A covalent bond is formed when sharing of electrons takes place between two atoms combining. This compound is formed when two non-metals combine.

Hence, the correct answer is ionic compound.

All atoms of the same element must have the same number of unitsFor 8:

For a given compound FeS. The chemical name for this compound is ferrous sulfide.

This compound is formed from the combination of iron and sulfur. Iron belongs to Group 8 and is considered as a metal. Sulfur belongs to Group 16 and is considered as a non-metal.

These two atoms will combine to form an ionic compound.

Thus, the correct answer is ionic compound.

For 9:

Weight is defined as the amount of gravitational pull that acts on an object having mass 'm'. It is expressed by an equation:

where,

W = weight

m = mass of the object

g = acceleration due to gravity

An object will have same mass on every planet but will have different weight due to the change in strength of gravity.

Hence, the correct answer is Weight.

For 10:

Calcium is the 20th element of the periodic table. The number of electrons this element has are 20.

The electronic configuration for this element =

Number of electrons that are present in third energy level (n = 3) for this element are 8.

Hence, the correct answer is 8.
