Answer:
The first five elements of the periodic table are:- hydrogen, helium, lithium, beryllium, boron
Explanation:
atomic number- it is represented by the letter Z. It is basically the total number of protons present in each atom's nucleus of that element.
atomic mass- is the mass of a single atom present in the element.
electrons and protons- they are negatively and positively charged particles found in the nucleus of the atom respectively.
neutrons- they have no or zero charge and weigh more than protons.
element | atomic number | atomic mass | electrons | protons | neutrons
hydrogen (H)- 1 | 1.008 | 1 | 1 | 0
helium (He) - 2 | 4.0026 | 2 | 2 | 2
Lithium (Li) - 3 | 6.94 | 3 | 3 | 4
beryllium (Be) - 4 | 9.0122 | 4 | 4 | 5
Boron ( B) - 5 | 10.81 | 5 | 5 | 6
B. has the storms strongest winds is not a characteristic of the eye of a hurricane because in the eye it is actually completely calm.
Hope that helps u!!
it is equal theres your answer np :)
Answer:
answer is option 2 hope it helps
The given reaction is:
C4H10 + O2 → CO2 + H2O
The above equation is not balanced due to the unequal distribution of atoms on either side of equation
# atoms Reactants # atoms products
C = 4 C = 1
H = 10 H = 2
O = 2 O = 3
In order to balance it, multiply C4H10 by 2, O2 by 13, CO2 by 8 and H2O by 10 to get:
2C4H10 + 13 O2 → 8CO2 + 10H2O
