Dokumen ini membahas tentang sejarah jadual berkala unsur dan pengelasan unsur. Jadual berkala unsur pertama dikembangkan oleh Dmitri Mendeleev pada tahun 1869 untuk mengelaskan unsur berdasarkan sifat-sifat periodik mereka. Jadual berkala membantu memprediksi sifat-sifat unsur yang belum ditemukan.
1) Elektrik statik terhasil apabila dua bahan berlainan digosokkan bersama-sama, menyebabkan pemindahan elektron antara kedua-dua bahan.
2) Bahan yang menerima elektron menjadi bercas negatif manakala bahan yang kehilangan elektron menjadi bercas positif.
3) Cas elektrik statik boleh dihasilkan dan dikesan menggunakan alat seperti elektroskop.

1) The document discusses sexual and asexual reproduction in humans. Sexual reproduction involves the fusion of male and female gametes during fertilization, while asexual reproduction involves only one parent and does not involve gametes.
2) It also describes the male and female reproductive systems, including the structures and functions of the testes, ovaries, sperm, and egg. Changes during puberty are also outlined.
3) The menstrual cycle, fertilization process, development of the embryo and fetus, and importance of prenatal care are explained in detail. Risks of smoking, drinking alcohol and inadequate nutrition during pregnancy are highlighted.
All living organisms are made of cells, which are the basic units of life. Cells come in different sizes and shapes, and can function independently to grow, respire, divide and excrete waste. Theodor Schwann asserted in 1839 that plants and animals are composed of cells. Cells are either unicellular, like bacteria, or multicellular, like humans, and organize into tissues, organs and body systems. The human body contains various cell types that perform specialized functions.

1. Kereaktifan logam diukur dengan tindak balasnya dengan oksigen, yang paling reaktif akan menghasilkan nyalaan terang sedangkan yang kurang reaktif akan menghasilkan pembakaran/perubahan warna.
2. Berdasarkan eksperimen ini, siri kereaktifan logam dibentuk dengan logam paling reaktif di atas.
3. Terdapat tiga kaedah pengekstrakan logam iaitu melalui elektrolisis, penurun
The document discusses Hildegard Peplau's interpersonal relations model of nursing. Peplau developed this model which focuses on forming common goals between nurses and patients. The model outlines four phases of the nurse-patient relationship: orientation, identification, exploitation, and resolution. In the orientation phase, the patient seeks help and the nurse helps them understand their problem. In the identification phase, the patient's dependence or independence is established. The exploitation phase involves the patient deriving value from the relationship. Finally, in the resolution phase, older needs are resolved and new needs emerge.
