Answer:

See explanation

Explanation:

In an atom, the inner electrons may shield the outer electrons from the attractive force of the nucleus. We, refer to this phenomenon as the <u><em>shielding effect</em></u>, It is defined as a decrease in the magnitude of attraction between an electron and the nucleus of an atom having more than one electron shell (energy level).

Shielding effect increases down the group due to addition of more shells but decreases across the period due to the increase in the size of the nuclear charge.

As the magnitude of shielding increases down the group, ionization of electrons becomes easier and the first ionization energies of elements decreases as we move down the group. Since shielding effect decreases across the period, the first ionization energies of elements increases across the period.

Answer:

Among the given options which one best suits the definition of an element?

Explanation:

Element:

Element is the pure form of matter which cannot be broken down into new simpler substances either by physical or chemical means.

It is made up of the same type of atoms.

For example:

Copper, silver, gold, oxygen, etc.

Among the given options:

the third option that is elements are made of atoms is the correct option.

Remaining statements:

Elements are made up of complex chains of carbon and oxygen is wrong,

Elements can be broken down into other simpler substances is wrong.

Because we don't get any simpler substances from elements.

For example, if we break a gold rod many times also only its size varies and no new substance is obtained from it.

All elements have the same chemical properties is a wrong statement.

Because each element is unique and it has its own properties.

victus00 [196]

Answer:

See explanation

Explanation:

The most accurate method of determining the volume of an object, is the water displacement method. It has the peculiar advantage of working well with irregular solids.

There are often errors that prevent exact measurements of the volume of objects. This makes the water displacement method a preferred and easier method of determining the volume of an object.

If you have a mass of 60 kg on earth, what is your weight in newtons?
AnnyKZ [126]
To calculate your weight in Newton's simply use the following equation to solve for the weight.

Fg = m • g
Fg = 60 kg • 9.81 m/s^2
Fg = 588.6 kgm/s^2

Fg = 588.6 N.

Acceleration due to gravity on earth is 9.81 m/s ^2.
