An ionic compound is a lattice of positive and negative ions held by strong electrostatic attraction, and that force explains all its other properties.

A covalent bond is formed when two atoms share one or more pairs of electrons so that each completes its outermost shell.

Sodium is a metal that gives up an electron easily and chlorine is a non-metal that accepts one, so the two form sodium chloride, an ionic compound.

Ionic compounds dissolve well in water but not in kerosene, petrol or other non-polar organic solvents, so this statement is not a property of theirs.

The element with atomic number 56 is barium, and its outermost electron enters the 6s orbital, so it sits in the s-block.

Relative atomic mass is measured against the carbon-12 atom, one-twelfth of whose mass is taken as the standard unit. That unit is the atomic mass unit, written u, and it is defined as exactly one-twelfth of the mass of one atom of carbon-12.

Ice melts at 0 degrees Celsius, and 0 degrees Celsius is 273 K on the Kelvin scale. To change Celsius into Kelvin, add 273 to the Celsius reading, so 0 + 273 gives 273 K; the melting point of ice is usually written as 273.15 K in exact work.

The balanced equation is 2FeSO4 → Fe2O3 + SO2 + SO3, so p = 2, q = 1, r = 1 and s = 1.

State Blood Transfusion Councils were felicitated at the national observance for their record in blood collection, and among the North-Eastern States, Mizoram stood first with Sikkim in the second position.

Give Blood. Save Lives." The Ministry of Health and Family Welfare set this theme for the observance, and officials explained that it points to the humanitarian spirit behind donation and calls on eligible citizens, particularly the young, to come forward.

The day is observed on this date every year to spread awareness about voluntary blood donation and to encourage healthy, eligible people to donate regularly and without payment.

The shramdaan and plantation drive named Ek Din, Ek Ghanta, Ek Saath is to be held at Purana Qila in Delhi in coordination with that body, which looks after protected monuments.

During the preparatory phase of the campaign, the Ministry of Culture, together with its attached, subordinate and autonomous organisations spread across the country, identified that many sites for cleaning.

The campaign is built in two parts. The first is a preparatory phase, which ran from the sixteenth to the thirtieth of September 2026, and in which each participating ministry fixed the cleaning and disposal targets it would meet.

It runs this government-wide drive, in which ministries and their attached, subordinate and autonomous bodies clean their premises, weed out old files and clear pending references.

The Secretary of the Department of Drinking Water and Sanitation stressed that villages under the two tribal missions should be reviewed regularly through meetings of this body, which is headed by the Deputy Commissioner or District Magistrate of the district.

DA-JGUA is one of the two tribal missions whose drinking water needs were reviewed by the Department of Drinking Water and Sanitation; the other is PM-JANMAN, the Pradhan Mantri Janjati Adivasi Nyaya Maha Abhiyan.

It has carried out a state-wise exercise named SurveySetu, in which the status of functional household tap connections is verified at the level of each household.

This is the dedicated provision set aside under Jal Jeevan Mission 2.0 for closing drinking water gaps in the tribal villages covered by the Pradhan Mantri Janjati Adivasi Nyaya Maha Abhiyan and the Dharti Aaba Janjatiya Gram Utkarsh Abhiyan.

The Ministry chose a working government precinct rather than a ceremonial venue, which fits the point it was making: that clean surroundings are the everyday responsibility of the people who use a place.
