Question

aleast do this sum urgent please
i will give u brainlist

Answer 1

Wanna, Its correct answer was that "BOTH THE ATOMIC/IONIC RADII" decreases as due to increase in the atomic no. on moving down the gp in lanthanoid series and this process was also known as "LANTHANOID CONTRACTION". Hope it helps you....... MARK IT AS A ""BRAINLIST"".

Answer 2

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers acrossEmission spectrumAn atomic emission spectrum is the pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains. ... Each of these spectral lines corresponds to a different electron transition from a higher energy state to a lower energy state.

Only carbon atoms can have 6 protons in the nucleus, and only oxygen atoms have a Z=8, meaning that there are 8 protons in the nucleus of the atom.
