1. Name the following:I. A species with more number of protons than electrons.II. An atom having stable electronic configuration.III. A molecule is formed by sharing of electrons.IV. A metallic atom having unstable electronic configuration.V. A subatomic particle with negligible mass. |
|
Answer» Answer: The total number or protons + neutrons is CALLED the mass number (sometimes called the nucleon number in Physics). The number of protons in an atom is called the atomic number (sometimes called the proton number in Physics). Below is Lithium (Li), it has 3 protons in the nucleus and 4 neutrons. Atoms are stable when they have EIGHT valence electrons (two in the case of hydrogen). This is called having an octet. Only the noble gases have an octet of valence electrons naturally (two for helium, which is called a duet). A covalent bond, also called a MOLECULAR bond, is a chemical bond that INVOLVES the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. An stable electronic configuration refer to an atom in which the OUTERMOST shell is complete.Whereas an unstable electronic configuration refers ta an atom in which the outermost shell is incomplete An atom consists of three subatomic particles namely electrons, protons and neutrons. Electrons are the negative charged particles, very tiny, have negligible mass. Protons are the positively charged particles, have greater mass than an electron, and are found in the center of an atom inside the nucleus. pls mark me as brain list. |

वायरस के बारे में बताएं |
|
Answer» अगर आपको खाने में चीजों का स्वाद नहीं मिल रहा है और आसपास की चीजों की गंध महसूस नहीं कर पा रहे हैं तो आपको सावधान हो जाना चाहिए. आपको कोराना की जांच जरूर करा लेनी चाहिए. केंद्रीय स्वास्थ्य मंत्रालय ने शनिवार को सूंघने और स्वाद की क्षमता में कमी को भी कोरोना वायरस के लक्षणों में शामिल कर लिया. इस मसले पर काफी समय से चर्चा जारी थी. राष्ट्रीय टास्क फोर्स ने व्यापक चर्चा के बाद इस बारे में फैसला लिया है. यह पाया गया है कि कोरोना सें संक्रमित लोगों में सूंघने और स्वाद महसूस करने की क्षमता में कमी आई है, इसलिए इसे अब संक्रमण के लक्षण में शामिल कर लिया गया है. कोरोना वायरस के संक्रमण को फैलने से रोकने के लिए इसके लक्षणों को पहचानना बेहद जरूरी है. लक्षणों को पहचानकर ही कोरोना वायरस को काबू में किया जा सकता है. इसके लक्षण फ्लू से मिलते-जुलते हैं. संक्रमण के फलस्वरूप बुखार, जुकाम, सांस लेने में तकलीफ, नाक बहना और गले में खराश जैसी समस्या उत्पन्न होती हैं. यह वायरस एक व्यक्ति से दूसरे व्यक्ति में फैलता है. इसलिए इसे लेकर बहुत सावधानी बरती जा रही है. कुछ मामलों में कोरोना वायरस घातक भी हो सकता है. खास तौर पर अधिक उम्र के लोग और जिन्हें पहले से अस्थमा, डायबिटीज़ और हार्ट की बीमारी है. स्वास्थ्य मंत्रालय ने कोरोना वायरस से बचने के लिए दिशानिर्देश जारी किए हैं. इनके मुताबिक, हाथों को साबुन से धोना चाहिए. अल्कोहल आधारित हैंड रब का इस्तेमाल भी किया जा सकता है. खांसते और छीकते समय नाक और मुंह रूमाल या टिश्यू पेपर से ढककर रखें. जिन व्यक्तियों में कोल्ड और फ्लू के लक्षण हों उनसे दूरी बनाकर रखें. अंडे और मांस के सेवन से बचें. जंगली जानवरों के संपर्क में आने से बचें. |
