Because Nucleus is composed of protons and neutrons..
anomalous behaviour of beryllium
Q. Define the Normality of solutions? Ans. Sometime normality is used to measure concentration. Normality (abbreviated N) is the number of gram-equivalent masses of solute in 1
Predicting the feasibility of reaction and does not show the rate of chemical reaction
To increase the pressure so that boiling point of water increases and heat provided goes only for cooking food not for boiling water
Chemical formula for calcium pyrophosphate is ca 2, P 2 O 1. The formula for ferric pyrophosphate will be: (1) Fe 3 (P 2 O 1 ) 3
A hydrogen-filled balloon was ignited and 2.00 of hydrogen reacted with 16.0 of oxygen.
Q. Show Anomalous Behaviour of Oxygen? Oxygen differs considerably from the rest of the family members. Small size, very high electronegativity and non-availability of d-orbita
Explain in words why hydroboration leads to anti-Markovnikov addition of hydrogen whereas most electrophilic addtions to alkenes result in Markovnikov addition.
0.22(6.022)(10^23)
Which type of bond is formed between similar atoms: (1) Ionic (2) Covalent (3) Coordinate (4) Metallic Ans: Covalent
in the nucleus of any atom,the no. of protons and the no. of neutrons are same.Also in the nucleus the protons and the neutrons are intermixed not remain seperated.In nucleus two protons never touch each other because between any two proton there is always a neutron which contradicts the force of repulsion.
BECAUSE THE REPULSIVE FORCE OF PROTONS IS LESS THAN THE ATRACTIVE FORCE BETWEEN NUCLEONS.
