Answer:
Recognizing the colors and identifying the color names is an important part of a child's development.Early identification of colors helps to create the cognitive link between visual clues and words.
Explanation:
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted.White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.~Hope this helps!
Answer:
5. All magnesium atoms have the same number of neutrons
Explanation:
Magnesium (Mg) is a chemical element. Its atomic number (Z) is 12 (number of protons in the nucleus of the Mg atom).
The Magnesium has three stable isotopes: 24Mg, 25Mg and 26Mg. All these isoforms have 12 protons in their atoms (same atomic number), however they vary in the mass number of the atom (M).
The mass number of the atom (M) is equal to the sum of protons and neutrons in the nucleus.
Based on this information we can know how many neutrons each isotope has
24 Mg = 12 protones + 12 neutrons
25Mg = 12 protones + 13 neutrons
26Mg = 12 protones + 14 neutrons
In this way we conclude that <u>not all magnesium atoms have the same number of neutrons</u>
