Element Be:
What is it's name?
What is its atomic number?
What is its atomic mass?
How many protons does it have?
How many electrons does a neutral Be atom have?
How many neutrons does it have?
The element Be is beryllium.
Its atomic number is 4.
Its atomic mass is approximately 9.01218 atomic mass units (amu).
A beryllium atom has 4 protons.
A neutral Be atom also has 4 electrons.
Beryllium typically has 5 neutrons, although the number of neutrons can vary in different isotopes of beryllium.
Element Be is Beryllium.
Its atomic number is 4.
Its atomic mass is 9.0122 atomic mass units.
Beryllium has 4 protons.
A neutral Be atom has 4 electrons.
The number of neutrons in Beryllium can be calculated by subtracting the number of protons from the atomic mass. Consequently, 9.0122 (atomic mass) - 4 (protons) = 5.0122 neutrons.
To find the answers to the questions regarding element Be, you can refer to the periodic table of elements. Here's how you can get each answer:
1. What is its name?
- The symbol "Be" stands for the element beryllium.
2. What is its atomic number?
- The atomic number of an element corresponds to the number of protons in its nucleus. You can find the atomic number of beryllium (Be) by locating it on the periodic table. In this case, Be has an atomic number of 4.
3. What is its atomic mass?
- The atomic mass of an element refers to the average mass of its isotopes, taking into account their abundance. The atomic mass of beryllium (Be) is also available on the periodic table, typically listed below the element's symbol. For Be, the atomic mass is approximately 9.01218 atomic mass units (amu).
4. How many protons does it have?
- The number of protons in an atom is equal to its atomic number. As mentioned earlier, the atomic number of beryllium (Be) is 4, which means it has 4 protons.
5. How many electrons does a neutral Be atom have?
- In a neutral atom, the number of electrons is equal to the number of protons. Since beryllium (Be) has 4 protons, it also has 4 electrons.
6. How many neutrons does it have?
- The number of neutrons in an atom can be determined by subtracting the atomic number (number of protons) from the atomic mass. For beryllium (Be), the atomic mass is approximately 9.01218 amu, and the atomic number is 4. Therefore, the number of neutrons in Be is approximately 9 - 4 = 5.
