One of the basic building blocks of matter, which cannot be broken down by chemical means is an element.

The first chemical element is hydrogen (atomic number is 1) and the last is oganesson (atomic number is 118).

Elements are scheduled in Periodic table, ordered by their atomic number.

Other example, krypton is a chemical element with symbol Kr and atomic number 36.

Krypton has 36 electron and 36. It is noble gas (group 18).

Noble gases are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.

Answer:

Nearly 80 per cent of organisations in North America and Europe were victims of cyber attacks last year and nearly half of cyber attacks used malware hidden in encrypted traffic to evade detection, a report said on Wednesday.

The encryption technology that is crucial to protecting sensitive data in transit such as web transactions, emails and mobile apps, can allow malware hiding inside that encrypted traffic to pass uninspected through an organisation’s security framework.

The report by US-based security company A10 Networks in partnership with Ponemon Institute surveyed 1,023 IT and IT security practitioners in North America and Europe, highlighting the challenges these professionals face in preventing and detecting cyber attacks.

The student placed 10 mL of PbCl2 (saturated solution) in the test tube and added a pinch of NaCl. A white precipitate of PbCl2
NNADVOKAT [17]
PbCl₂(aq) → Pb²⁺(aq) + 2Cl⁻(aq)

NaCl(aq) → Na⁺(aq) + Cl⁻(aq)

Pb²⁺(aq) + 2Cl⁻(aq) ⇄ PbCl₂(s) 

At increase the concentration of chloride ions - concentration of lead ions decreases, the lead chloride is formed.
